According to Osho, when realization arises through the touch of water, the subtle, clear contact breaks through the mind's layers and one instantly recognizes one's innate Buddhahood - pure isness - beyond the personal "I". This awakening can happen in an ordinary bath or shower if sensitivity and totality are present, and, once seen, it is retained as a stable, ever-present awareness.
Feeling water completely can suddenly show you your true self, and that knowing stays.
