Torrents of passion well within water signs and they feel things deeply. However, water signs are always emotionally reserved, no matter what impression they might give on the surface. Still water, it as been said, runs deep, and the mystery about water pertains to this group (especially Scorpio).
A water sign will always become quiet or withdrawn when they are trying to sort things out. It will take some time to get to know them well, for they reveal themselves slowly. They realize their intense emotions hold tremendous power, and they tend to handle their feelings carefully. When they fall in love, water signs love with their whole hearts and all their devotion. Their sensitivity makes them highly romantic, even sentimental. Often psychic, water signs read your true intentions simply by reading your gestures and body language and will trust actions more than words (Pisces, particularly, has elevated this talent to high art).
Water cleanses us and sustains life on earth. Water is the universal solvent, breaking substances down--dissolving them--and taking on their qualities. Therefore, when you share a problem with a water sign, they take on your problem as if it were their own. Their ability to sympathize and empathize is awesome; you'll get their full attention, a shoulder to cry on, and some excellent advice to boot. Because they give of themselves so readily, water signs need regular time alone to regain their center.
