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.
Silence makes the secretions of the mind visible. By emptying myself when I fast, emptying myself in solitude, I might discover myself full -- of history, wilderness and society. And I can see my identity co-evolving with all of creation ... I willingly entered the Valley of the Shadow through solitude, silence, stillness, meditation, and prayer. In those quiet places, I discovered a mindstream whose depths were luminous.
