Zen Master Dōgen

When the great Chinese Zen master Ta-mei was dying, his students asked him for a final helpful word. "When it comes, don't try to avoid it; when it goes, don't go running after it," said Ta-mei. Just then, a squirrel chattered on the roof. "There is only this, there is nothing else." he said, and then he died.
