The purpose of meditation practice is not enlightenment; it is to pay attention even at unextraordinary times, to be of the present, nothing-but-in-the-present, to bear this mindfulness of now into each event of ordinary life.
Certain redwood groves are holy places for me because they capture silence and light. The forest is so dense as to exclude all external noise. It is possible to ignore their silence until a single bird sings within. When the single song has died not only do I realize I have heard a sound exquisite in its simplicity, but also that I have heard it so precisely because it was embedded in pure silence.
