Dharma transmission
While seeking out a teacher who could confirm his enlightenment, he found Kobong, who told him to keep a not-knowing mind. In the fall of 1948, Seung Sahn learned dharma combat while sitting a one-hundred day sesshin at Sudeoksa—where he was known to stir up mischief, nearly being expelled from the monastery. After the sesshin was concluded, he received dharma transmission ("inka") from two masters, Keumbong and Keum'oh. He then went to see Kobong, who confirmed Seungsahn's enlightenment on January 25, 1949 and gave him dharma transmission as well. Seung Sahn is the only person Kobong gave Dharma transmission to. He spent the next three years in observed silence.
