Kamalashila

Kamalaśīla (fl. 740–795) was an Indian Buddhist of Nalanda Mahavihara who accompanied Śāntarakṣita (725–788) to Tibet at the request of Trisong Detsen.

Dargyay, et al. (1977, 1998: p. 7) convey a lineage of transmission and translation of Śīla, Sutrayana Buddhavacana and the Six Pāramitā (viewed principally through the Mahayana teachings of Nagarjuna), from India to Tibet (pandit in this context denotes a Sanskrit scholar):

The Indian pandits, represented mainly by Śāntarakṣita, Kamalaśīla, and his disciple Ye-śes-dbang-po, form a known group. These scholars were all defenders of the Madhyamaka school, which is based upon Nāgārjuna's teachings. First of all, however, they taught the ten rules of behaviour of the Buddhist ethics (śīla) and a summary of the teachings according to the canonic Sūtras of the Mahāyāna, as well as the virtuous works of the six pāramitās. These exercises are supposed to lead, in a long seemingly endless way, to the gradual ascent to the acquisition of higher intellectual abilities finally culminating in Buddhahood. This trend was intensified after the debate of bSam-yas had taken place in the years 792 to 794; the exact outcome of this debate is still debatable.

in 793 Trisong Detsen resolved that Moheyan did not hold the true dharma. Following intense protests from Moheyan's supporters, Trisong Detsen proposed to settle the matter by sponsoring a debate, the "Council of Lhasa", although it may actually have taken place at Samye, a considerable distance from Lhasa. Kamalaśila was invited to represent Vajrayana while Moheyan represented the East Mountain Teaching of Chan Buddhism. Most Tibetan sources state that the debate was decided in Kamasila's favour (though many Chinese sources claim Moheyan won) and Moheyan was required to leave the country and that all sudden-enlightenment texts were gathered and destroyed by royal decree. This was a pivotal event in the history of Tibetan Buddhism, which would afterward continue to follow the late Indian model with only minor influence from China. Moheyan's teachings were a mixture of the East Mountain Teachings associated with Yuquan Shenxiu and with the teachings of Baotang Wuzhu.
