If we can be perfectly quiet and perfectly still with no attempt to overcome, destroy, remove, or escape from any situation or condition, the flow to the Spirit will rush in and there will be freedom.
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.
