I began to discover a phenomenon which I now call Mutual Affinity. It comes from the principle that astrological influences are flexible and to a certain extent, interchangeable. For example, having the Sun in Sagittarius has much the same effect as having the Sun in the ninth house, or having the Sun in aspect to Jupiter. Similarly, it also corresponds to having Jupiter in Leo or in the fifth house. So, how did this work in my own chart?
I have my Sun in the first house of my chart. The first house is the equivalent of Aries, therefore it has a natural affinity with the Sun in Aries. I also have my Mars in Leo which is another variation of the Sun in Aries, so double the effect. A Sun sign Aries whom I've had a close personal relationship with for the last 14 years has his Moon conjunct my Moon and his Sun is actually square my Ascendant, so fantastic synastry. He is a very good and trusted friend, and we have lots of fun together. In fact, I trust this guy more than anyone else in my life.
There's a person I met recently who is a perfect example of another component in the Mutual Affinity technique. This involves having similar astrological traits in both charts. For example, we both have our Suns in Air signs and both our Suns are conjunct Saturn. We both have Aquarius Moons and his Sun is in aspect to Uranus - a direct correlation to my Sun in Aquarius. He also has Mercury in aspect to Saturn, I have Mercury in Capricorn and his Saturn is in Gemini.
Of course, on its own, Mutual Affinity isn't enough to trigger or sustain an important relationship, but it is fantastic in a platonic friendship as it brings a sense of being on the same mental wavelength which allows two people to enjoy each other's company in a completely uncomplicated way. Try out Mutual Affinity on your own chart and see how you interact with your friends. Let me know what you find, and remember, I'm always here to answer any questions.
