What water tends to mean
Emotion, intuition, healing and cleansing. Commonly placed in the west, and often represented by a bowl or cup.
Finding it today
A glass from the tap. Rain on a window. Washing up. A bath. 'Moon water' (water left out overnight under the moon) is a popular modern practice rather than an old one.
A small practice
Wash your hands slowly and deliberately, deciding as you do what you are setting down. That is a genuine cleansing practice.
Moon water is widely taught online as ancient. It is actually a modern practice, not an old one, which does not make it worthless, only recent.
