There's a place beyond David Deida's 3rd Stage relationship model of holding the masculine and the feminine at later stages of developmental consciousness. It's pretty well accepted that to get to later stages of development, you have to pass through the earlier stages.
I think it's true for 3rd Stage relationship, as well, on its way to the beyond.
This is a place where the masculine and the feminine both drop away, where the lines separating them cease to exist, and where it's no longer important how each other carry the masculine and the feminine in "real-ationship."
It's what I'm calling "fusion."
It's melting into non-dual awareness, two breaths becoming one, the breath becoming the entry point into the "fusion" of emptiness and form into a pure blissful state of the one. It is pure concsiousness from which everything....everything....else arises.
