There is only this now. It does not come from anywhere; it is not going anywhere. It is not permanent, but it is not impermanent. Though moving, it is always still. When we try to catch it, it seems to run away, and yet it is always here and there is no escape from it... When Fa-ch'ang was dying, a squirrel screeched on the roof. "It's just this," he said,"and nothing else."

-Alan Watts, The Way of Zen
