In 1981 he received inka from Seung Sahn, making him a Ji Do Poep Sa Nim (JDPSN) in the lineage and, in 1983, he was ordained a sunim and given the Buddhist name Mu Deung.1 He received Dharma transmission on October 11, 1992. On July 17, 1994, Su Bong died of unknown causes at a retreat while conducting kong-an interviews in Hong Kong.
