李成桂
Hyujeong (, 1520-1604), also called Seosan Daesa (서산대사, 西山大師) 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.
