Interpreting Cusps




One explanation for how cusps work. Why 29 degrees Aries and 2 degrees Torus are so different?

In astrology we take the positions of planets and relate them to where they are in orbit around the sun. This orbit is split apart between 12 signs, each taking up 30 degrees of the circle. When the planet falls well within the 30 degrees of a sign it is clear applying metaphor is clear. Sometimes these planets fall very close to the next sign, however, and in these cases there can be a mix between the metaphors between the two signs. We call this on the cusp. In this case looking at 29 degrees Aries and 2 degrees Torus will be much different than than 15 degrees Aries and 18 degrees Aries. So why do these cutoff lines matter?  What is really happening when we get really close to entering the next sign? Why does the interpretation of cusps sometimes incorporate a little guessing and further exploration?

Interpreting the cusps can be quite an art. There can sometimes be a fascinating mix between the two signs, and other times a clear switch into the next energy. Over time, as I study more of the physical nature and makeup of astrology, this metaphorical understanding has become increasingly helpful. It explains why the “fuzziness” of interpretation is more toward the end of a signs cycle, and not as much as the beginning of another. It also explains how a few degrees can create such a clear shift energetically. To start we are going to talk about cymatics.

Cymatics shows a visual representation of the frequencies present. There are many forms of cymatics, all of them illustrate this principle in different ways. In the video below watch what happens when the devise goes though distinct resonant frequencies.

As you can see as each new frequency snaps the sand into a new shape. Near the end of a frequencies range the sand gets fuzzy then snaps to the new frequencies geometric representation. In astrology the cusps work in the same way. Near the last degree it starts to get a little fuzzy then snaps into place for the next resonate frequency once you enter the next sign. The reason why this happens only in the last degree or two is because each degree is actually rather large. Consider Saturn rotating around the sun, for example. That one degree can take up the span of days. Like the video above, as the planet enters the last phase of the previous energy, or sign, it gets a little fuzzy, then once it inters the new sign it takes form with the new energies present.

This may vary from year to year as well. Each planet isn’t all alone; rather, they are all orchestrated together. Therefore, it is quite possible that during some years and with certain geometric configurations, that the length of this “fuzzy” period may be extended or even exasterbated. So you have it, a clear metaphor and principle to understand just why cusps matter and why astrologers need to ask a few questions when someone is on a cusp to see which sign is most influencing their chart. Essentially it must be discovered just how “fuzzy” the mix of energies was for them so they konw how much of the current sign and how much of the next signs metaphors should used and to what extent. Perhaps with time we will begin to undertsand these concpets with further detail and develop algorythems to predict accuracy at these stages. Before we get there a few personal questions can usually clear up any questions as to if you lean more into one sign or another.
