Imagination and creativity are linked to water and our psyches. In modern psychology water is the symbol of the unconscious and water imagery is linked to dreams. It's a feminine principle – emotive, receptive and endowed with characteristics of the mother.
Used in purification rituals and in Christian baptisms; to be immersed in water signifies a return to the pre-formal state – birth on the one hand, death on the other. Water symbolizes potential, which precedes all creation and form.
