Daosui
Dàosuì (道邃, Jp: Dōzui, floruit 796–805) was Tang dynasty Buddhist monk from Chang'an and a student of the Tiantai patriarch Zhanran 湛然 (711–782). Daosui is known for transmitting the Tiantai teachings to Saichō, the founder of the Japanese Tendai school and is thus considered to be the seventh patriarch of the Tendai tradition. Daosui was posthumously honored with the title Xingdao Zunzhe (Venerable One Who Promotes the Way). He was also commonly referred to as Shikan Washō (Master of Śamatha-Vipaśyanā).
