A technique which I just devised that pertains to synastry is to check all ten planets between the two charts you are comparing, to see which signs are left out, that is, which signs have no planets in them in either chart. These will represent the types of energies that the two people mutually don’t work with. As to the importance of looking at this, I think it will become much stronger if there is just ONE sign that the two people do not have between them. For that means that there is only ONE energy lacking between the two people, which, if consciously compensated for could serve to bring a fuller energy of completeness to the relationship.
My friend Tyler and I only lack Capricorn. For all the other eleven signs of the zodiac, either he or I has at least one planet there. But we both lack Capricorn. And I think what this means is that we need more efficiency – that is to say, what are we doing, and why? Is it practical? How could we get to where we are going with less expenditure of energy? These are all Capricorn concerns.
Continuing with this idea of synastry by looking only at planets in signs, Akiko has planets from the signs Taurus through Sagittarius, with Cancer, Leo, and Libra left out, and I DO have planets in these three signs. So I’m completing her span. On the other hand, looking at how her planets fit in to my chart, I have planets in all the signs she has them in, except for SCORPIO, where she has Neptune. So her Neptune in Scorpio is like a special gift to me, and not only that, but my planets span the signs from Taurus to Sagittarius, with only SCORPIO left out! So we are both completing each other sequences – filling in missing. Which doesn’t surprise me at all, for it certainly feels like she is providing me with missing pieces, and bringing a greater completeness to my life.
