The power of quiet is great. It generates the same feelings in everything one encounters. It vibrates with the cosmic rhythm of oneness. It is everywhere, available to anyone at any time. It is us, the force within that makes us stable, trusting and loving. It is contemplation contemplating us. Peace is letting go -- returning to the silence that cannot enter the realm of words because it is too pure to be contained in words. This is why the tree, the stone, the river and the mountain are quiet.
The spiritual function of fierce terrain (in the apophatic tradition) is to bring us to the end of ourselves, to the abandonment of language and the relinquishment of ego. A vast expanse of jagged stone, desert sand, and towering thunderheads has a way of challenging all the mental constructs in which we are tempted to take comfort and pride, thinking we have captured the divine. The things that ignore us save us in the end.
