Thanh Hư Đường Tập (Tây Sơn Đại Sư)

Also known as Seosandaesa

Hyujeong (, 1520–1604), also called Seosan Daesa () was a Korean Seon master. As was common for monks in this time, he travelled from place to place, living in a succession of monasteries. Buddhist monks had been forced to keep a low profile since General Yi Seonggye had been forced to eject Buddhism from its state of total permeation of government in order to gain the support of Neo-Confucian scholar-officials to consolidate his position against his Buddhist political opponents when he overthrew Gongyang of Goryeo in 1392 to become King Taejo of Joseon.
