Orthodox Zen followers generally blindly take this incident to be the origin of their doctrine, in which, according to them, is disclosed the inmost mind of the Buddha as well as the secret of the religion. As Zen claims to be the inmost essence of Buddhism and to have been directly transmitted by the Buddha to his greatest disciple, Mahākāśyapa, its followers naturally look for the particular occasion when this transmission took place between the master and the disciple. We know in a general way that Mahākāśyapa succeeded the Buddha as the leader of the Faith, but as to his special transmission of Zen, we have no historical records in the Indian Buddhist writings at present in our possession. This fact is however specially mentioned for the first time as far as we know in a Chinese Zen history called _The Records of the Spread of the Lamp_,[4.2] compiled by Li Tsun-hsü, in 1029, and also in _The Accounts of the Orthodox Transmission of the Dharma_ compiled by Ch‘i-sung in 1064,[4.3] where this incident is only referred to as not quite an authentic one historically. In _The Records of the Transmission of the Lamp_,[4.4] written in 1004, which is the earliest Zen history now extant, the author does not record any particular event in the life of the Buddha regarding the Zen transmission. As all the earlier histories of Zen are lost, we have at present no means to ascertain how early the Zen tradition started in China. Probably it began to be talked about among the Zen followers when their religion had been well established in China late in the eighth century.
