Satori as the Raison d'Être of Zen
Essays in Zen Buddhism
Text
Satori is the raison d'être of Zen, without which Zen is not Zen. All the intellectual content of Zen, if there is any, comes from satori. Without satori there is no Zen, for the life of Zen begins with the opening of satori. It is the sudden flashing into consciousness of a new truth hitherto undreamed of. It is a sort of mental catastrophe taking place all at once, after much piling up of matters intellectual and demonstrative. The piling has reached a limit and the whole edifice has come tumbling to the ground, when behold, a new heaven is open to your full survey.
