Entering into silence is like stepping into cool clear water. The dust and debris are quietly washed away, and we are purified of our triviality. This cleansing takes place whether we are conscious of it or not: the very choice of silence, of desiring to be still, washes away the day's grime.
A person's life purpose is nothing more than to rediscover, through detours or art, or love, or passionate work, those one or two images in the presence of which that person's heart first opened.
