We can now see how Zen developed out of this system of spiritual exercises. Zen adopted the external form of dhyana as the most practical method to realise the end it had in view, but as to its content Zen had its own way of interpreting the spirit of the Buddha. The dhyana practised by primitive Buddhists was not in full accord with the object of Buddhism, which is no other than the attaining of Enlightenment and demonstrating it in one’s everyday life. To do away with consciousness so that nothing will disturb spiritual serenity was too negative a state of mind to be sought after by those who at all aspired to develop the positive content of the Buddha’s own enlightened mind. Tranquillisation was not the real end of dhyana, nor was the being absorbed in a samadhi the object of Buddhist life. Enlightenment was to be found in life itself, in its fuller and freer expressions, and not in its cessation. What was it that made the Buddha pass all his life in religious peregrination? What was it that moved him to sacrifice his own well-being, in fact his whole life, for the sake of his fellow-creatures? If dhyana had no positive object except in pacifying passions and enjoying absorption in the unconscious, why did the Buddha leave his seat under the Bodhi-tree and come out into the world? If Enlightenment was merely a negative state of cessation, the Buddha could not find any impulse in him that would urge him to exertion in behalf of others. Critics sometimes forget this fact when they try to understand Buddhism simply as a system of teaching as recorded in the Agamas and in Pali Buddhist literature. As I said before, Buddhism is also a system built by his disciples upon the personality of the Buddha himself, in which the spirit of the Master is more definitely affirmed. And this is what Zen has in its own way been attempting to do—to develop the idea of Enlightenment more deeply, positively, and comprehensively by the practice of dhyana and in conformity with the spirit of general Buddhism, in which life, purged of its blind impulses and sanctified by an insight into its real values, will be asserted. _Zen and, the Laṅkāvatāra_
