of the Buddha, for they only reflect one side of it and fail to take an inner and comprehensive view of the whole field. If these critics took up the practise of dhyana as constituting the essence of Buddhism along with the above considerations, they may be said to have come nearer to the goal; but even this dhyana is a form of spiritual exercise which will prepare the way to the final realisation of Nirvana. Dhyana in itself does not distinguish Buddhism from the other philosophico-religious systems which existed in India in the day of the Buddha. Therefore, to understand Zen as expressing the Doctrine of Enlightenment which is the reason of Buddhism, we must wait for the rise of the Mahayana movements. And when this was introduced into China by Bodhi-Dharma, it grew up to what we now know by the name of Zen Buddhism. I The legendary story of the origin of Zen in India runs as follows: Śākyamuni was once engaged at the Mount of the Holy Vulture in preaching to a congregation of his disciples. He did not resort to any lengthy verbal discourse to explain his point, but simply lifted a bouquet of flowers before the assemblage, which was presented to him by one of his lay-disciples. Not a word came out of his mouth. Nobody understood the meaning of this except the old venerable Mahākāśyapa, who quietly smiled at the Master, as if he fully comprehended the purport of this silent but eloquent teaching on the part of the Enlightened One. The latter perceiving this opened his golden-tongued mouth and proclaimed solemnly: “I have the most precious treasure, spiritual and transcendental, which this moment I hand over to you, O venerable Mahākāśyapa!”[4.1]
