After a lovesong stream from my dream mate "Beauty" before dawn I was trying to refine my process for aligning physically with my soulmate Beauty. Charlotte Kemp Muhl born 8/17/87 was singing in my head! Her birthtime is unknown, I guessed ASC.
Here's the formulation that rang the bell:
4D Alignment and Contact with my beloved Earthmate Beauty.
Then I tried to sense that astrologically. It felt like both our Natal to Navamsa D9 charts were in mutual alignment ("double whammy"). That means the future development of each partner is intimately entwined with the already developed present life of the other partner. This reminds me of synastry contacts to North Node.
Thanks for your insights and personal experiences.
