VIII ғасырдағы буддалық монах Хэшаң Мохэян және Ласа кеңесі

8th century Buddhist monk

Heshang Moheyan was a late 8th century Buddhist monk associated with the East Mountain Teaching. Moheyan (摩訶衍) is a brief translation of Mahayana in Chinese, so the name literally means a Mahayana monk. He became famous for representing Chan Buddhism in the so called "Council of Lhasa," a debate between adherents of the Indian teachings of "gradual enlightenment" and the Chinese teachings of "sudden enlightenment," which according to tradition was won by the "gradual teachings."

Hwashang is a Tibetan approximation of the Chinese héshàng "Buddhist monk This, in turn, comes from the Sanskrit title upādhyāya "teacher".

Whilst the East Mountain Teachings (known as the "Northern School" Chan) were in decline, having been attacked by Shenhui (a student of Huineng) as a supposed "gradual enlightenment" teaching, Moheyan traveled to Dunhuang, which at the time belonged to the Tibetan Empire, in 781 or 787. For Moheyan, this was a new opportunity for the spread of (Northern) Chan.

After teaching in the area of Dunhuang, Moheyan was invited by Trisong Detsen of the Tibetan Empire to settle at Samye, then the center of emerging Tibetan Buddhism. Moheyan promulgated a variety of Chan Buddhism and disseminated teachings from Samye where he attracted a considerable number of followers. However, 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 most famous of these debates has become known as the "Council of Lhasa", although it may have taken place at Samye, a considerable distance from Lhasa. For the famed Council of Lhasa, an Indian monk named Kamalaśīla was invited to represent Indian Buddhism, while Moheyan represented Chinese Chan Buddhism. In the so called “Great Debate” that the sources tell us took place at the then newly founded monastery of Bsam yas between 792 and 794 c. e., the renowned Indian scholar Kamalaśīla is supposed to have debated the Chinese Ch’an master, Hwa shang Mahayana. The Tibetan sources tell us that the debate (shags) took place before the emperor. Kamalaśīla was the advocate of a “gradualist” (rim gyis pa) position, the view that enlightenment is attained through the incremental purification of the mind that takes place by the practice of the six perfections. This path, he held, requires analytical mental activity and a commitment to the intentional accumulation of merit. Hwa shang held the “simultaneist” (cig car ba) view—that (for advanced adepts at least) enlightenment is not attained gradually through the purification of the mind, that for these individuals analytical activity is a distraction and the accumulation of merit unnecessary. Instead, he claimed, enlightenment, as something that is already immanent in the individual, can immediately be accessed by directing the mind internally, by ceasing mentation, and by becoming aware of the nature of mind itself. Most of the Tibetan accounts tell us that Kamalashila won the debate, and this is said to have sealed the fate of Tibetan Buddhism forever. King Khri srong lde’u btsan, who served as “arbiter” or “judge” (dpang po) in the debate, declared that henceforth Tibetans would follow the Indian Buddhist tradition, in particular the system of Nagarjuna. Most Tibetan sources state that the debate was decided in Kamalaśīla'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. Nevertheless, Chan texts were produced until the 10th century in Tibet, which casts doubt on these Tibetan sources. and "no examining" (pu kuan = myi rtog pa) or "no thought no examining" (pu ssu pu kuan = myi bsam myi rtog). "Gazing at mind" is an original Northern (or East Mountain Dharma Gate) teaching. As will become clear, Poa t'ang and the Northern Ch'an dovetail in the Tibetan sources. Mo ho yen's teaching seems typical of late Northern Ch'an. It should be noted that Mo ho yen arrived on the central Tibetan scene somewhat late in comparison to the Ch'an transmissions from Szechwan. The dichotomy of the gradual north and sudden south is a historical construction, as both Northern and Southern Schools contained "gradualist teachings" and "sudden teachings" and practices.

The teachings of Moheyan and other Chan masters were unified with the Kham Dzogchen ("Great Perfection") lineages through the Kunkhyen (Tibetan for "omniscient"), Rongzom Chokyi Zangpo. The Dzogchen of the Nyingma was often identified with the subitist ("sudden enlightenment") of Moheyan, and was called to defend itself against this charge by avowed members of the Sarma lineages that held to the staunch view of "gradual enlightenment"
