It was not till a thousand years had passed since the introduction of Buddhism into China, and not till four hundred years after Bodhidharma had brought the Zen form of it there, that the koan technique assumed any prominence at all among the methods of meditation. Even to this day one of the two Japanese Zen schools, the Soto, makes only little use of koans.
