In the early 1970s, when I first began to study heliocentric astrology and was able to create for myself a helio ephemeris, I was fascinated by heliocentric planetary nodes. This was years before home computers. With the help of my friend David W. Wilson and a mainframe computer, we calculated this complete nodal system. Here is a brief introduction. For those who want to know more on this topic or who want lists of these nodes at various epochs, please see my book “Interface: Planetary Nodes,” which is once again available in paperback on Amazon.com.
Astrology is all about nodes. Nodes are sensitive points in the natal chart that can be interpreted. Obvious examples of nodes are the Nodes of the Moon. The Ascendant, Midheaven, Vertex and other sensitive horoscope points are nodes. The traditional twelve House Cusps are also nodes. Since most astrologers do not consider latitude when calculating aspects, even aspects are nodes.
We may be familiar with the above nodes, but what about planetary nodes? What are they?
What is a Node?
I had been studying astrology for some number of years before I understood what a node was, for example the Ascendant or Rising Sign that all astrologers mean when they ask: “What is your rising sign?”
Back then, my rising sign in Sagittarius, was to me just that: a point in the zodiac, in my case in the sign Sagittarius. It was not until much later that I understood that all nodes are intersections of two independent systems of one kind or another. In the case of my Ascendant, the zodiac was one system, but I had to research to find out the other, which turned out to be the Local Horizon.
The Ascendant is a Node
So the Ascendant is the intersection or interface between the plane of the zodiac and the plane of the local horizon, to the East. This was news to me and sent me scurrying to figure out what the other nodes I had always been using interfaced with.
For example, the Nodes of the Moon are the intersection of the plane of the Moon’s orbit with the plane of Earth’s orbit, the zodiac.
Or the Vertex is the intersection of the plane of the zodiac with the plane of what is called the Prime Vertical, a Great Circle running from East to West through the local Zenith. And so it went. You get the idea.
Nodes or Interfaces
The point here is that any node is an interface and intersection between two great circles or planes, very often involving the familiar zodiac. This book is about planetary nodes, the nodes or interfaces that are formed when the planes of any two planets intersect. And by intersect, I don’t just mean intersect with the planet of the earth’s orbit, but the planes of any two planets intersect with each other, with or without Earth being one of the two.
Two planetary planes intersect to create what we could call a sensitive point, more like a power point for that matter. As the planets travel around their orbits through time, they reach these power points or nodes two times in a complete orbit or cycle. At that point, the planet is not only in the plane of its own orbit, but simultaneously in the plane of the second planet, and this is a point of power or emphasis. This book is about the system of planetary nodes and how to interpret them in your own natal chart. I call these planetary nodes: “Interface Points.”
Where it Started for Me
The interface concept came out of my interest in heliocentrics, in particular an inquiry into the mutual inclination (or lack thereof) of the various planes of our solar system, planes like that of the ecliptic, equator, horizon, galaxy, supergalaxy, and so on. I was fascinated by the different attitudes or inclinations of the various astronomical planes, each to the others. What could these mean?
A whole series of astronomical coordinate systems exist, each with their own center and plane of reference. More interesting to me is that fact that these many systems are oriented to each other, differently — are set in space at different angles to one another. They are set in space like some grand crystal. Perhaps they represent whole approaches to life, each with its own independent attitude or stance.
I was interested to note that astrologers devote their attention to the zodiac or ecliptic, but seem to pay little or no attention to these other planes: the Horizon, Prime Vertical, and Celestial Equator. Astrologers seem not to grasp or care that points such as the Ascendant, MC, Vertex, etc. are not zodiac points alone, but are nodes representing the intersection of the zodiac with some other great plane. In fact, it takes two independent planes to create a node. This important fact seems to have been lost in modern astrology.
Even within our own solar system, each of the great planetary orbits has its own plane and particular orientation or attitude. Each of these great planetary orbital planes are oriented or inclined to the others. An attempt to reduce all these intersecting orbital planes -- this grand planetary crystal -- to the set of the most significant points or nodes was how the interface nodal technique came into being.
Introduction to the Concept
As mentioned, astrologers use a variety of coordinate systems to look at life. The most well known, of course, is the zodiac or ecliptic system, but there are also the equatorial system of right ascension & declination, the horizon system of azimuth & altitude, the prime vertical system of longitude & amplitude, and still others.
On a grander scale, there are still other coordinate systems that are fascinating in their own right , including the local system of stars of which our Sun is a member, our own galactic system, and even a supergalactic system, of which I have written elsewhere (“The Astrology of Space.” All in all, we have several major coordinate systems in common use by astrologers such as the ecliptic plus half a dozen or so esoteric systems that are little used, which brings me to concept of interface analysis.
Interface analysis is a reduction of all of the nine planet's orbital planes, their inclinations and disinclinations to one another, to the particular series of zodiac points that represent both symbolically and physically the only points in the zodiac at which these various inclinations and disinclinations intersect and are exact or in perfect alignment.
When a planet (moving in its own orbit) comes into alignment with the orbital plane of a second planet (passes through or over that point), it is at one of the two nodes (ascending or descending) with that plane. I call these nodes ‘Interface Points’. Therefore, an inclination or nodal alignment (interface) refers to an exact planar alignment between two planet’s orbits (where the two planes intersect to form a node) and this will emphasize (for better or for worse) the nature and function of the planets involved. On the other hand, planets at DIS-inclination (at 90-degree points in their orbit to the nodes or interface points) represent these same principles as they are when most mutually disinclined — each to the other. It may help to offer a brief summary of the astronomical basis for this concept.
The Basic Astronomy
In the above diagram we see the Sun at the center of the solar system and Earth going counterclockwise (Looking down from above the Sun) in its almost circular orbit each year. The earth always stays in its orbit and that orbit defines a plane running through the center of the Sun and Earth. That plane geometrically extends infinitely in all directions, dividing the heavens into two halves, one above the orbit of the earth (and Sun) and the other below that orbit. This is standard high-school astronomy.
Earth’s Orbital Plane
Here is the same diagram, but looking more or less from the side now, but at just enough of an angle so that you can see the ellipse of Earth’s orbit. The earth’s orbit, which defines the familiar zodiac or ecliptic, is the primary reference plane used by astrologers.
Nodes to Earth’s Orbit
What is a node? As we know, each of the nine planets orbits around the Sun in a large ellipse, with the Sun as the center. This orbital ellipse of the earth and any planets defines a plane passing through the center of the Sun. The planes of the orbits of the nine planets in our solar system do not happen to coincide (do not orbit in the same plane), but, instead, are inclined to one another, slightly. The line defined by the intersection of the planes of any two planetary orbits is called the line of nodes.
In the above diagram we can see the orbit of the earth and the orbital plane of the planet Jupiter. Note that these two orbital planes cross each other to form two intersections or interfaces. These are the planetary nodes of Jupiter and Earth. Both the ascending and descending nodes are marked in the diagram.
Other Planetary Nodes
Our solar system has the Sun at its center and this is known as the heliocentric celestial sphere. Since all of the planetary orbital planes pass (by definition) through the center of the Sun, the planes all intersect the celestial sphere in what are called great circles. Therefore, each intersecting planetary plane has a distinct pair of nodes with each of the other planets, thus the system of planetary nodes.
This pair of nodes for each planetary pair (Mercury-Venus, Mars-Saturn, etc.) represents the two points in the zodiac (ascending and descending nodes) where either planet is simultaneously in both planes at once.
Nodes to Earth
For example, the planetary nodes of all the other planets with respect to the Earth (i.e. where their planes intersect the Earth's orbital plane — the ecliptic) and the inclinations of these planes to the Earth's orbital plane are known to astrologers, although even these points are not often used in modern astrology.
There is, however, some small reference in the astrological literature to a planet being at its node in the plane of the Earth. For instance: Jupiter might be sighted as being at its northern or southern node to the Earth plane, and yet seldom (almost never) do we find reference to the Earth being at this same nodal point (and in the Jupiterian plane), although this happens without fail twice a year! At these times, the Earth moves into alignment with the Jupiter plane and takes on some of the qualities of that planet.
The Jupiter-Earth Interface
In the above diagram, you can see where the plane of Jupiter’s orbit intersects with the plane of Earth’s orbit.
My point is that: while astrologers have embraced and often use the concept of planetary pairs when it comes to aspects, we have managed to ignore these nodal pairs, although they are at least as physically valid as aspects. As we know, astrologers have a plethora of riches when it comes to the myriad points and techniques available to them.
Until this writing (1976), almost no attention has been given to the fact that each pair of planetary orbits intersect one another to produce their particular set of nodal intersections, irrespective of the orbit of the Earth. It is this last category that is the particular subject of this book.
The Planetary Nodes Exclusive of Earth
The Earth is but one planet, albeit a very important one to us, in our solar system. What we are examining here (which are not so familiar, although easily computed) are the nodes (points in the zodiac) where any two planets' orbital planes (irrespective of the Earth's plane) intersect. This article is concerned with the location of the entire system of planetary-pair nodal points (interface points) as they can be measured along the zodiac.
Locating the Nodes
Let's consider any two planets other than the Earth, for example: Jupiter and Saturn. The planes of their orbits make great circles on the Celestial Sphere as does the plane of Earth's orbit. Where these two great planes intersect one another are the planetary nodes or interface points for this particular planetary pair. Now let’s zoom in on where these three planes (Earth, Jupiter, and Saturn) interface.
Close Up of n Interface Point
Note that these points are located slightly above or below the zodiac plane (Earth plane), but not right in it. Since most astrologers have only the zodiac as their plane of reference, it is convenient to use this zodiac in order to point out activities in these other planes. With the help of mathematician David W. Wilson and using spherical trigonometry, we have projected these points on to the astrological zodiac (ecliptic), so that by watching either Mars or Saturn transit a given point in our zodiac (using the heliocentric ephemeris), we can know that the planet (either Mars or Saturn) is simultaneously at its interface and exactly in the plane of the second planet. The result is an easy way for us to tell when a planet is at a particular interface point, by using a standard heliocentric ephemeris.
In the above diagram, we are looking at the ascending or northern node the Saturn plane to the Jupiter plane, the Saturn-Jupiter interface point. This is marked by point “C.” The point where Saturn crosses Earth’s plane (zodiac) is point “B,” and the point where Jupiter crosses the zodiac is point “A.” If we project point “C” down to the zodiac at point “D,” then whenever either Jupiter or Saturn reach point “D” using any heliocentric ephemeris, we can know that the planet (Jupiter or Saturn) is then at is interface point to the Jupiter and Saturn plane.
In other words, the tables at the end of this article list the points in the zodiac when the particular planetary-pair node or interface is exact in the planes of the two planets involved. Now let's look at the system of interface points from a less technical viewpoint.
Nodal Points in Astrological Work
Let us briefly review the use of nodes in modern astrology:
As mentioned earlier, astrology is very nodal, more than one might at first imagine. This article concentrates on the planetary nodes. However, just in passing, you may wish to note that standard points like the Ascendant and Vertex are nothing more than nodes. And it always takes the planes of two independent coordinate systems to create a node.
While astrologers are aware that points like the Ascendant and Vertex are zodiac points, many are not aware that the Ascendant (for example) is brought to you by means of the zodiac AND another independent plane, that of the Local Horizon. The Ascendant is where they intersect, the intersection of the plane of the zodiac and the plane of the local horizon to form a line of nodes.
Still fewer astrologers know that the Vertex is made available by the intersecting plane of the Prime Vertical coordinate system (again, to the plane of the zodiac). In fact, most of the hot spots of astrology are where two coordinates systems come together to intersect and create an interesting set of nodes or points. So much of our astrology concerns itself only with the familiar zodiac that there is little awareness of the many supporting systems of coordinates that are also in effect.
Representing the interrelationship of the orbital plane of the moon with that of the Earth, the lunar nodes are widely used and understood by practically all modern astrologers, both in the East and the West. There are several good texts available on these nodes and I refer you to those.
The use of the planetary nodes in modern astrology is generally restricted to the nodes of the various planets as they intersect the orbital plane of the Earth (the zodiac or ecliptic). The planar interfacial angles of the other planets relative to each other (planetary nodes) have been practically ignored.
As an example of this ignorance, let me cite the continual reference in the astrological literature to a planet being at its node in the plane of the Earth. For instance: Jupiter, as pointed out earlier, is often cited as being at its northern or southern node — and yet seldom (almost never) do we find reference to the Earth being at this same nodal point (and in the Jupiter plane) although, as mentioned above, this happens two times a year. At these times, the Earth moves into the Jupiter plane and takes on some of the qualities of that planet.
Interface: Mutual Intersection
In brief, the primary reason why the planetary nodes are not more widely used and appreciated by astrologers is the failure to realize these points in their reciprocity – equal-“ness.” A planetary nodal point, by definition, represents the mutual intersection of two independent (planetary orbital) planes. We have chosen to call these nodal points ‘Interface Points’, as this word emphasizes the reciprocal nature of any single point and plane. A node points both ways.
Realization of these nodal lines as planetary pairs that represent the nature of both planets involved will result in more wide-spread use of these interface points and their incorporation into the body of technique as practiced by the astrologers of today.
In summary, the structure of our solar system is in fact defined by the interrelationship of the various orbital planes of which it is composed. This interrelationship is conveniently expressed by the complete system of planetary nodes and their square points. In this introduction to the use of these nodes by astrologers, we will confine ourselves to activation of these nodal points by direct transit at the Interface node shared by any two planets and activation by transit to points square (at ninety degrees) from these interface nodal points. Let’s discuss the “Square Points.”
The 90-Degree or Square Points
In the above diagram, note points “A” and “B.” This are the points in the orbit when the planet is ‘square” or 90-degrees from either node. At these ninety degree or square points, a planet reaches what is astronomically termed its point of greatest latitude (either north or south) to the plane of the second planet involved. These points of greatest latitude are those points where the planet is most highly disinclined (literally) to the plane of the second planet and simultaneously changes reference from one node and begins to move (in its orbit) toward a conjunction with the opposite node.
In the above diagram, Jupiter is 90-degrees from either the ascending or descending node, and is as dis-inclined to Earth as it ever gets. Point “B” is the opposite point, beneath the earth’s orbital plane.
Therefore, you will note that at these Square Points we have a changing-line of relationship, while at the interface nodal points themselves, we have the simple activation or direct function of the principles involved.
To repeat: activation of the interface points themselves by transit of either of the two planets involved results in simple emphasis and clear function. For instance: one planet will be, by transit, in the plane of the second. The second planet (somewhere in its own orbit) is always in its own plane and yet, for a time (long or short, depending on the planets involved), the first planet is, by transit, exactly in this same plane and may be said to take on some of its qualities, whether by resonance or some other undetermined means.
It is important to have in mind which plane is being activated and which planet is, by transit, active in that plane. Is Mars by transit in the plane of Saturn or is Saturn transiting in the plane of Mars or both — which happens occasionally. These distinctions, at first perhaps somewhat confusing, will become clear with some study and you may be satisfied, to begin with, keeping simply in mind that the Saturn/Mars Interface is in activation.
Questions of Interpretation
The simple and very defined structure and interrelationship of these various points tend to dictate concerning questions of interpretation, and one advantage to this approach is that very little is left to the imagination which, for some astrologers, can be a decided blessing. The relationships are clear:
The northern (or ascending) node of a planet is that point where the planet transits a given plane in what is called a south to north direction (from under to above the given plane). The southern or descending node is a transit from north to south (above to below the given plane). Above and below are defined by the position of the north pole of the ecliptic.
A given planet (such as Jupiter) transits a node to the plane of a second planet (say, Saturn), at which time Jupiter is perfectly in the plane of the second planet, Saturn. Jupiter then continues along its orbit (away from that node) until the point is reached of greatest latitude (whether north or south) in relation to the nodal interface in question. From that moment onward, the planet (Jupiter, again) proceeds to move toward the opposite nodal point for the particular planetary pair and once again (at the opposing node) comes directly into the plane of the planet to be transited, Saturn.
Therefore: matters of interpretation are somewhat simplified and restricted (at least at first) to an analysis of the various quadrants: transit to the nodes and to the points of greatest disinclination (above and below) to these nodes.
Activation of the meaning of the interface points themselves needs no lengthy introduction here since there are many fine texts available that spell-out every possible planetary combination. Students are referred to Reinhold. Ebertin's “The Combination of Stellar Influences” as one of the best of its kind, although sometimes a bit dark or too heavy. I have also written all of these combinations as well, and they are available in some of my books and software programs.
Changing-Lines or Square Points
Although the planetary combinations are well known from other forms of astrology, we will spend some time here in the presentation of the principles involved in an understanding as to the use of the Square or Changing-Line points. These changing-line points, when activated, represent simultaneously two ideas:
(1) A planet at these points is as out-of-plane and therefore as disinclined as it can ever be to the plane of the second planet.
(2) At the same time the planet is changing its relationship to the nodal axis itself — away from one node and toward the opposite node.
A close study of these changing points will reveal much as to changing (uneasy, dis-eased, disinclinations, etc.), while the interface points themselves offer the more straight-forward function of the planetary pairs (nodes) involved.
Consideration of all the planet’s orbits simultaneously presents an ever-changing — almost kaleidoscopic effect — very similar to that obtained when rotating a fairly complex crystal in sunlight. Mutual harmonics and complex interrelationships are revealed that often highlight a single planet — again and again.
Therefore it is entirely possible, using only the interface points and their changing-lines or square points to reveal a structure indicative of the whole-life force of the individual or event being examined. In practice, however, best results are obtained when interface analysis is combined along with other traditional heliocentric or geocentric astrological techniques.
The Planes or Chakras
Although this is not meant primarily to be an section on the interpretation of the various planets and the planes they describe, some brief mention of the principles involved in such an interpretation is warranted. The planes or levels described by the planets are exactly similar to what in the Eastern tradition are termed chakras, the centers of force and activity which make up the whole of our life. A particular individual, while a part of this whole system, is usually more active and concerned with one level of their lives than with the others, at least at any given time.
Interface analysis has proved to be a great help in locating the specific level (chakra or plane) and planet to which an individual naturally responds. Once this is revealed, information is easily forthcoming of direct interest to the individual concerning the particular plane of life and initiation in which they are finding themselves involved.
Inner the Key to the Outer
For a more complete description of these various planets or chakras — please see my book “Astrology of the Heart – Astro-Shamanism.” The basic idea may be expressed here in one sentence: the key to the outer will always be the inner or in other words: the key to a given planet (chakra) will usually be that planet whose orbit is immediately within or inside the planet in question.
A perfect and clear example: the planet immediately within the Earth's orbit is Venus and for all time the Earth has been ever concerned with Venus or love and, in fact, divine love has always been put forth by the world's spiritual lights as the very key to life on this planet.
Initiation in the Planes
This is equally true for all planets from and including Saturn into the Sun (The outer planets have a different significance). It should be understood that, although we live by virtue of our birth on this planet, we are not by that fact automatically in full realization of our Earth existence. In fact, initiation within inner planes (planets) is a gradual process of graduation, by degrees.
The majority of us have great difficulty working through (for instance) the Saturn (Satan), Jupiter (succession), and Mars (marriage) to even get in possession of the Earth (the Heart or child) much less graduating to the inner planes of Venus (divine love), Mercury (light of love), and on to the Sun (Self or 1000-petaled chakra).
Levels of Life
As remote and "flowery" (or vague or abstract) as the above sentences may seem to some readers, it is important to understand these various planes and to realize that we in fact find ourselves endlessly involved, evolving, and revolving through this life. At any one time a given individual will be taken up with concerns of a given plane or chakra. It becomes of great importance to the counseling astrologer to accurately indicate at what level and plane the life is being extended or occurring and to what plane the individual may be referred to for more light and a clear answer as to the questions they may have.
In practice, the role of the astrologer often involves directing and referring individuals to the level or chakra which happens to be the key to their current life's concern. Interface Node analysis can help astrologers to more accurately and without personal bias determine the levels or planes to which a given individual responds as well as the key or level to be recommended as a way to these inner planes.
In the past, astrologers have too often been limited and restricted in their practice to those chakras or planets in which they personally may have taken initiation (understand from personal experience) and they have primarily worked only with those clients who exist on an outer planet or plane of initiation from their own level -- less aware than they are.
It is possible using Interface analysis for the astrologer to accurately determine and to direct a client to the appropriate level or plane, regardless of whether he or she personally has (or has not) taken that particular initiation. To do this with accuracy demands a relatively absolute frame of reference to which all matters may be referred. The simple structure of our solar system is such a framework and when properly understood and rigorously applied, much of what amounts to guesswork in the practice of astrology is removed.
The Astrologer of this Aquarian Age
Since the primary use of astrology in my life has been to confirm my own inherent nature and to explain to myself what I find happening around me, I would like to mention briefly some benefits of this technique of a more personal and yet still absolutely useful nature. To cite a personal instance: in my natal heliocentric configurations, I have the planets
Venus/Neptune/Jupiter mutually inclined to each other. In my younger (and not-so-younger) years, one source of concern and confusion for me involved periodic encounters with people with whom I didn't by nature get along. Some folks even took a dislike to me. Imagine that!
I always wondered why and I spent an unwarranted amount of energy and time searching myself to discover what I could have done to offend or to deserve such a reception. After all, we would all prefer to be loved and appreciated.
Exploring Interface Nodes
With this in mind, it was most satisfying, not to mention fascinating, to discover in the helio natal charts of these particular individuals who seemingly took offense to myself, that they had one or more planets at the changing-line or square point to my natal Jupiter/Venus or Neptune. In other words, they were most definitely disinclined to the planets to which I was by nature perfectly inclined.
Seeing this spelled out to me in their natal configurations has helped me to realize the simple fact of these inclinations/disinclinations, and to let pass the endless opportunities to search and question myself as to the fault -- on either part -- for this fact.
On the other hand, I was interested to discover that in almost every instance, my closest personal friends all had the same planets at the same degree and that this degree was an Interface point that was perfectly complementary (inclined) to myself -- my inclinations. This was (in my life) a rather remarkable discovery and one with the most practical kind of benefits to me as to the time and energy previously wasted in a useless self-examination. This is an example of how astrology has benefited me. Enough said.
A System of Notation
It remains for us to discuss a convenient system of notation by which to represent these Interface points, as they are found in a given chart. Such a system must include the planets themselves in their order from the Sun outward. A vertical column (like the spinal column) is perhaps symbolically the most correct.
Taking a particular natal or event chart (heliocentric only), we examine each planet's position and compare these positions to the list of interface points. We will want to notate activity at both the Interface points and the square or changing-line points.
The yellow column in the center represents the planetary planes, much like the chakra centers said to be along the human spine. It is useful to think of this column in that way.
To the left of that column are the moving or transiting planets, planets that are at the Interface Point with another planet. If a planet is listed on the left, it means it is at the interface point and thus ‘in the plane’ of the planet listed in the central column. It is ‘inclined’ and in the plane of the other planet, the one listed in the central column
If a planet is listed to the right of the central column, it means this planet is at the Square Point (Changing line) and is ‘disinclined’ or at the 90-degree pointed between the two nodes and as ‘not in the plane’ as physically possible.
Using this system of notation, you can see at a glance even complex arrangements of Interface and Square Points. Whole little trees can be read at a glance.
Interface Tree for Baba Ram Das
I have included below the "trees" of several well known individuals. You will note that the tree for Baba Ram Das, who personally withstood public opinion concerning the greatly feared psychedelic drug LSD, has the Interface Jupiter-Pluto simultaneously activated by both Pluto and Jupiter. These planets are also in conjunction in this natal chart (helio).
Jupiter (Sanskrit: Guru) represents the Life Path or literally the “way to go,” and Pluto represents transformation, so these mutually reciprocal planets are clear and easy to interpret.
Interface Tree for Howard Hughes
The tree for Howard Hughes has another mutual activation, in this case between Jupiter and Venus. What could be a better indication of wealth than a Venus-Jupiter combination? In Hughe’s case, he has both planets, each at the other’s interface. Jupiter is at the interface (and thus in the plane) of Venus, and Venus is at the interface (and thus in the plane) of Jupiter.
Interface Tree for Beethoven
And Beethoven's chart has an extraordinary emphasis on the planet Pluto, as does that of Baba Ram Das. You will also note that the planes or chakras most active in the Hughes chart are the middle-body chakras (Mars and Jupiter), while Baba Ram Das is more active in the outer planets. Beethoven sort of has the whole interface tree lit up. Points of disinclination show in Beethoven's chart some difficulty with the Mars principle (the marriage or emotions), while in the other diagrams Mercury and Earth are featured in DIS-inclination.
It remains for those of you who can respond to the ideas presented here to investigate for yourselves this fascinating subject and determine its usefulness in your particular work. In our understanding, what is revealed through this system of Interface points is exactly what is presented in the whole of chapter four of the Book of Revelations.
Note: Attempts to apply these points to the geocentric natal chart would be practical only with the outer planets, where the difference between geo and helio positions is plus or minus about three degrees and with the Earth/Sun axis, which is identical in either coordinate system. It is time that modern astrologers exercise their understanding of the fact, in addition to our lives on earth, we live simultaneously the lives of our solar system and Galaxy. We share a common fate. The heliocentric coordinate system may still be new to astrologers as a system of measurement, but the experience to which it refers is not new. It is where we came from and still are living.
Age of Aquarius
The religions of this world have long championed a more inclusive reality and each of us has for days or parts of days in our lives sustained awareness of this greater life. We have in fact arrived at a point where this experience can be measured and studied. As astrologers, we can point out to the world the opening in our times of what has been called the Age of Aquarius, a time of group work and mass understanding (initiation).
What more appropriate sign of this new age might we expect than a more holistic representation of this larger self to which we are true and an ability to refer and measure this self through coordinate systems of increasing inclusiveness. The net result is not a desertion of the geocentric (body) perspective, but rather the enhancement of that perspective, "To see eternity in a grain of sand."
As astrologers we are concerned with realizing eternity as it exists captured in the geocentric circumstances inherent in individual existence. We do not forsake the geo for the helio, as some have suggested. We in fact live at once through all time and all space and: This is it! All coordinate systems demonstrate this principle and exist only as they are convenient modes in which to measure and realize Eternity.

Reading the Interface Tables
In the following pages, there are Interface Tables for 1900, 1950, and 2000. The all follow the same format, so let’s go over it.
01°Ar02' MA-NE 01°Li02'
04°Ar02' MA-JU 04°Li02'
09°Ar27' EA*JU 09°Li27'
11°Ar31' VE+MA 11°Li31'
The first listing is “01°Ar02',” which is for the Mars-Neptune interface. It’s opposite nodal point is “01°Li02'.” Two planetary names linked by a hyphen indicate the zodiac position of that node for the particular epoch. The next listing is for the interface node for Mars-Jupiter.
The third listing “11°Ar31'” is for Square Point for Venus-Mars, and this is indicated by the “+” which stands here for “Square Point.” It’s opposite Square Point is at “11°Li31'” which is in zodiac terms 11 degrees of Libra 31’.
A dash between two planets: an Interface Point.
An “*” between two planets: Interface Point to Earth.
