The Traditional Model of the Cosmos, Part V: The Doctrine of Visibility

Here is the 5th installment of what will be a six-part series on the Traditional Model of the Cosmos. This video discusses the Doctrine of Visibility from an Essentialist perspective.

The parable is from The Image of the Cosmos.

The Moon’s Nodes, What Do They Mean?

There are some topics in Western Astrology in which there is a widespread consensus. The meaning of the Moon’s Nodes is not one of them. This article will talk about what the Nodes are and discuss various approaches taken by Modern, Classical, and Indian Astrology. Finally, I will talk about the approach that I have developed in my own practice.

What are the Moon’s Nodes?

From the Earth, it looks like the Sun travels through the sky in a circular path which is the same every year. This path is known as the ecliptic. The other planets, including the Moon, all have orbits that vary somewhat from the ecliptic. The Moon’s path varies about 5°. Because the path of the other planets varies from the ecliptic, they all cross the ecliptic twice along their orbit. The places where they cross are known as the planet’s nodes.


Of the planetary nodes, it is the nodes of the Moon that are of the greatest significance. This is because, from the perspective of the Earth, the apparent size of the Moon is the same as the apparent size of the Sun. Thus, whenever there is a New Moon near one of the Nodes, there is a Solar Eclipse, and whenever there is a Full Moon near one of the Nodes, there is a Lunar Eclipse.

Modern Karmic Interpretation

In recent years, the most commonly used interpretation of the Moon’s Nodes is that they relate to personal karma. In this interpretation, the South Node relates to one’s past lives and the North Node relates to one’s future. A complex version of this method of interpretation is put forth by Steven Forrest in his book, Yesterday’s Sky.  In this method of interpretation, Steven Forrest explains how he uses the South Node’s sign, house position, and ruler as well as the planets that aspect the South Node to tell a story about a person’s past life. He makes no claim that this story represents a factual past life. Instead, he claims that the themes of the story are what is important and that by understanding these themes, one can heal from one’s karma. From this idea, he has developed an entire branch of astrology, known as Evolutionary Astrology.

Not all Modern astrologers go this far, but the use of the South Node to indicate past lives and the North Node to determine one’s future direction has become widespread.

Other Modern Interpretations

While the karmic interpretation of the Nodes seems to be extremely popular in the present day and age, it seems to be a relatively recent one. For example, in an astrology textbook from 1971, The Compleat Astrologer, by Derek and Julia Parker, there was no mention of the karmic interpretation. In this book, the North Node was described as beneficial and having characteristics similar to Jupiter, and the South Node was described as adverse and having characteristics similar to Saturn.

In her book, Classical Astrology for Modern Living, by J. Lee Lehman, Ph.D., Dr. Lehman discusses a Nodal Cycle that seems to have been derived from Dane Rudhyar. This cycle traces the Moon’s path along the ecliptic as it travels across the North Node, reaches her Northernmost point, travels South, crosses the South Node, keeps going until she reaches her Southernmost point, and then travels North again. Dr. Lehman gives complete delineations for each of these stages when they are found in a Nativity Chart.

Classical/Traditional Western Interpretation

There seems to be a fair about of confusion and ambiguity about the meaning of the Nodes in the Western Tradition. In Book 1 of Christian Astrology, William Lilly reports that “the Ancients” considered the North Node, or the Head of the Dragon, to be of the nature of Jupiter and Venus and a Fortune. According to him, the Ancients taught that the North Node was good when conjunct good planets and evil when conjunct evil planets. In contrast, the South Node, or the Tail of the Dragon, is evil when joined with good planets and good when joined with evil planets.

After this description, William Lilly disputes with this interpretation, saying “upon what reason grounded I know not.” He says that he as always found the North Node to be the equivalent of the Fortunes and that:

when joined with the evil Planets to lesson their malevolent signification; when joined with the good to increase the good promised by them. For the Tail of the Dragon, I always in my practise found when he was jointed with the evil Planets; their their malice or the evil intended thereby was doubled and trebled, or extremely augmented.

He then wrote that when the good planets were joined with the South Node the good that was promised by them was disrupted and often came to nothing.

In his book, Hellenistic Astrology, Chris Brennan discusses a variety of approaches to the Nodes taken by astrologers in the Hellenistic Tradition. Some viewed both of them as negative because they were the places that eclipses formed. This was particularly true when either of the luminaries was found with them. The approach of “the Ancients” that William Lilly described seems to have been recorded as far back as Rhetortius of Egypt in the early Sixth or Seventh Century.

Rahu and Ketu in Vedic Astrology

In Vedic Astrology, the North Node is named Rahu and the South Node is named Ketu. Rahu and Ketu are considered planets in their own right. According to myth, the Devas and the Asuras worked together to churn to the ocean to create a substance called Amrit, which was a nectar that would grant immortality.  The Asura stole the Amrit for themselves, but Lord Vishnu took an incarnation as a beautiful woman, Mohini, to distract the Asura and take back the Amrit.



Mohini then went to the Devas to distribute it. One of the Asura, named Svarbhanu changed his appearance to obtain some of the Amrit. He sat between the Sun (Surya) and the Moon (Chandra), but they recognized him and exposed him to Lord Vishnu, who severed Svarbhanu’s head. Svarbhanu had already received a drop of the Amrit, and thus, did not die, but remained forever split in two. The head is Rahu and the tail is Ketu. Since that time, they have taken revenge against the Sun and the Moon by swallowing them, but as the Sun and Moon are also immortal, they always emerge intact.




Rahu is the head and has a mouth with no stomach. This means that Rahu can never be satisfied. Rahu is what we desire but can’t get enough of. In contrast, Ketu represents the things that we have no interest in and that bring us no pleasure.

How I Use the Nodes

Given the diversity of opinions on the Nodes and what they do, as a practicing astrologer, if one is to use them, one must work out what to do with them. For myself, the one thing that is clear about the Nodes is that they are the places where eclipses form.

Metaphysically, eclipses are the temporary triumph of Darkness over Light. As such, I view both of the Nodes as malefic influences. In a birth chart, if a person’s Sun is within 16° of either Node, that person was born during an Eclipse Season. The person is also likely to experience one or more eclipses by secondary progression in their lifetime.

In my own research, I have noticed that people who were born into eclipse seasons tend to be heavily impacted by larger social events or movements on a personal level. This impact is not always traumatic, but it often is. If they were born between eclipses, this impact will influence their entire life, but its power will dissipate somewhat when they progress into an un-eclipsed Lunation (New or Full Moon). The direct effect will largely subside at the first uneclipsed New Moon, although they will still bear the scars. If a person progresses into an Eclipse season, the impact will begin at that time rather than at birth.

For those who were not born during or progress into an Eclipse season, I treat the Nodes as collective karma rather than as individual karma. I look at their position in the chart and their interaction with other planets to determine where and how collective karma impacts the native.

In addition, I have considered integrating the principles of Rahu and Ketu, and I have seen some positive results in my initial research. On the other hand, I am a little dubious of “mixing and matching” principles in this way.
