Kim Gu
In 1944, he went to the Doksungsan Sudeok Temple, where he studied under Mangong Song Wolmyon (만공 송월면, 萬空 宋月面). Mangong was top of the Korean Ganhwaseon (看話禪, 간화선). He trained for Mangong. In 1946 he returned to Mangwol Temple (망월사, 望月寺) as its head. Chunseong was attacked for hypocrisy, rigorism, pretended philanthropy and formalism.
