Shenhui(684 - 758)
菏泽神會
Chinese Chan master and reputed main disciple of the sixth patriarch Huineng; his collateral branch of Huineng’s lineage is sometimes referred to as the Heze school. Shenhui was a native of Xiangyang in present-day Hubei province. He became a monk under the master Haoyuan (d.u.) of the monastery of Kuochangsi in his hometown of Xiangyang. In 704, Shenhui received the full monastic precepts in Chang'an, and extant sources provide differing stories of Shenhui's whereabouts thereafter. He is said to have become a student of Shenxiu and later visited Mt. Caoxi where he studied under Huineng until the master's death in 713. After several years of traveling, Shenhui settled down in 720 at the monastery of Longxingsi in Nanyang (present-day Henan province). In 732, during an "unrestricted assembly" (wuzhe dahui) held at the monastery Dayunsi in Huatai, Shenhui engaged a monk by the name of Chongyuan (d.u.) and publicly criticized the so-called Bei zong (Northern school) of Shenxiu’s disciples Puji and Xiangmo Zang as being a mere collateral branch of Bodhidharma's lineage that upheld a gradualist soteriological teaching. Shenhui also argued that his teacher Huineng had received the orthodox transmission of Bodhidharma's lineage and his "sudden teaching" (dunjiao). In 745, Shenhui is said to have moved to the monastery of Hezesi in Luoyang, whence he acquired his toponym. He was cast out of Luoyang by a powerful Northern school follower in 753. Obeying an imperial edict, Shenhui relocated to the monastery of Kaiyuansi in Jingzhou (present-day Hubei province) and assisted the government financially by performing mass ordinations after the economic havoc wrought by the An Lushan rebellion in 755. He was later given the posthumous title Great Master Zhenzong (Authentic Tradition). Shenhui also plays a minor, yet important, role in the Liuzu tan jing ("Platform Sūtra of the Sixth Patriarch"). A treatise entitled the Xianzongji, preserved as part of the Jingde chuandeng lu, is attributed to Shenhui. Several other treatises attributed to Shenhui were also discovered at Dunhuang. Shenhui's approach to Chan practice was extremely influential in Guifeng Zongmi's attempts to reconcile different strands of Chan, and even doctrine, later in the Tang dynasty; through Zongmi, Shenhui's teachings also became a critical component of the Korean Sǒn master Pojo Chinul’s accounts of Chan soteriology and meditation.

Buddha-nature, Critical Buddhism, and Early Chan
This article begins with a reflection on why medieval Chinese Buddhist thought has not been more conspicuous in recent comparative work on Buddhism and Western philosophy. The Japanese proponents of "Critical Buddhism" (hihan bukkyō 批判仏教), Matsumoto Shirō 松本史朗 and Hakamaya Noriaki 袴谷憲昭, would see this neglect as merited since, in their view, East Asian Buddhism in general, and Chinese Chan in particular, is philosophically crippled owing to its embrace of tathāgatagarbha and buddha-nature thought. Indeed, Matsumoto singles out Shenhui 荷澤神會 (670-762), one of the architects of the Southern School of Chan, as an example of the early Chan advocacy of buddha-nature doctrine.
This article is not concerned with whether buddha-nature and tathāgatagarbha thought is actually deleterious to critical philosophical work. Rather, the concern is to demonstrate that, far from embracing buddha-nature doctrine, the eighth-century founders of Southern Chan had serious concerns with it. Evidence for this is found in: (1) the writings of Shenhui, notably in his opposition to the doctrine of the "buddha-nature of insentient objects" (wuqing foxing 無情佛性); and (2) the Platform Scripture of the Sixth Patriarch (Liuzu tanjing 六祖壇經), particularly in the variant versions of Huineng's famous "enlightenment verse." Thus the Southern School may be viewed as a forerunner of the Critical Buddhist anti-dhātuvāda polemics. The article closes with comments on the ongoing problems Chinese Buddhist exegetes had in marrying the metaphysical monism of Yogācāra and tathāgatagarbha teachings with the anti-foundationalist thrust of Madhyamaka and Prajñāpāramitā literature.

Shen-hui and the Teaching of Sudden Enlightenment in Early Ch'an Buddhism
No abstract given. Here are the first relevant paragraphs:
The field of Ch'an studies has seen some very lively disputes over the course of the twentieth century, but there has been general agreement on the proposition that the doctrine of sudden enlightenment represents the highest expression of the doctrinal mainstream of early Chinese Ch’an Buddhism. Although there is some quibbling regarding details and specific interpretations, scholars working in this field often describe the history of the doctrine of sudden enlightenment within Ch’an in terms of three subjects: (1) Hui-neng’s doctrine of sudden enlightenment as shown in his "mind verse" (hsin-chieh) in the Platform Sutra of the Sixth Patriarch (Liu-tsu t'an-ching); (2) Shen-hui’s campaign in opposition to the gradual teaching of the Northern school and in support of the public recognition of Hui-neng as sixth patriarch; and (3) the continuation of the spirit of Hui-neng in the teachings and religious practice of Ma-tsu, Shih-t'ou, and the later Ch’an tradition
Research done in recent years has shown that the traditional interpretations of these three subjects are all substantially incorrect, although the implications of these findings have not yet been fully realized. The history of early Ch'an is in the process o f being thoroughly rewritten, but it is already clear that the doctrine of sudden enlightenment and the dispute between the sudden and gradual teachings should no longer be used as yardsticks by which the religious message of Ch'an and its widespread acceptance in T'ang dynasty China are understood. (McRae, "Shen-hui and the Teaching of Sudden Enlightenment in Early Ch'an Buddhism," 227)

Sudden and Gradual
This volume examines the historical basis of the debate over sudden versus gradual approaches to enlightenment in Chinese Buddhism, seeing it as part of a recurrent polarity in Chinese history and thought. Sudden and Gradual includes essays by Luis O. Gómez on the philosophical implications of the debate in China and Tibet, Whalen Lai on Taodheng's theory of sudden enlightenment, Neal Donner on Chih-i's system of T'ien-t'ai, John R. McRae on Shen-Hui's sudden enlightenment and its precedents in Northern Ch'an, and Peter N. Gregory on Tsung-mi's theory of sudden enlightenment. (Source: Motilal Banarsidass)
