up all conceptions, an automatic, all-at-once attainment of virtue resulted. He taught that there was an "internal" practice to gain insight and liberate one-self, and an "external" practice to liberate others (upaya, or skillful means). These were seen as two independent practices, a concession to human psychology and scriptural tradition. According to José Cabezón: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. Teachings Sudden teachings Moheyan’s teachings were a mixture of the East Mountain Teachings associated with Yuquan Shenxiu and Baotang Chan. Broughton gives the following
