Aquarius and Pisces are very different creatures, in a sense. Aquarius is an air sign, meaning that it lives in its mind. Air, in astrology, stand for mental processes. Of thinking, reasoning, of approaching life rationally, of finding answers, of exploring, of learning new things. Pisces is a water sign, deeply water. Water, in astrology, stands for emotion, of feelings, of creativity, of searching for some kind of spiritual, sexual, emotional connection that is a bonding of the soul, of the psyche. And so we have here two people with very different approaches to life. They will find each other interesting to start with. Aquarius loves to play with sex; too, is very inventive, very innovative in its lovemaking. Pisces adores sexy sex and can give adoration and can give that sense of fantasy and of deep connection. But all too soon these two will drift apart because Aquarius doesn't like all of that emotional possessiveness. Doesn't like anything cloying or needy. What Pisces needs, particularly, is to have a relationship that is great togetherness. Doing things together, being in life together as deep partners. And so, if you look at it in terms of air and water, the air in Aquarius stands for wanting to be free and exploring and flying outward into the air and the water for Pisces is the waters of feeling and emotion and being in the deep waters of a sexual and emotional bonding. The energies just don't work well together.
