 During his years of practicing in hermitages he also studied Sasang Constitutional Medicine (SCM) under two renowned acupuncturist/herbalists.One of them was so impressed with Sunim's diligence and special skills in quickly understanding the principles of SCM that when he retired from his practice he gave all his journals and notes to Sunim for his own reference.In 1985 he was invited by Hae Heng, a French monk who had studied in Songgwangsa, to become the spiritual director of the Buddhayana Vihara Zen Center in Geneva Switzerland.
