Zen in its essence is the art of seeing into the nature of one’s own being, and it points the way from bondage to freedom. By making us drink right from the fountain of life, it liberates us from all the yokes under which we finite beings are usually suffering in this world. We can say that Zen liberates all the energies properly and naturally stored in each of us, which are in ordinary circumstances cramped and distorted so that they find no adequate channel for activity. *****************This volume being third in the series emphasises on the relationship which exists between Zen and the two chief Mahāyāna sutras, the Gandavyūha and the Prajñāpāramitā, and then the transformation through which Indian Buddhism had to go while adapting itself to Chinese psychology. The Gandavyūha and the Prajñāpāramitā had to be converted into Zen dialogues to be appreciated by the Chinese.
