It represents needs, nourishment, the emotional self, feminine/receptive/Yin, the subsconscious mind, and the soul or superconscious mind. IMHO it's more important than the Sun, but then I'm a "Moon programmer" -when people's Suns can't solve their problems they come see me.
I have a question about what I think is a stillenium ?
My moon is in sagittarius not conjunct to but also with a venus/neptune conjunct. what happens when all your planets live in stilleniums and how best to serve your needs when they are all grouped together conjunct or same house? x
