Zen Master Su Bong passed away while giving an interview during retreat in Hong Kong on 17th July 1994. His death demonstrated what in Zen teaching is called “entering Nirvana while sitting or standing”. Before he passed away, he often encouraged students to practice together. In memory of the teaching of Zen Master Su Bong, we organised a 3-day retreat at Gak Su Temple on 15 – 17 July. During the ceremony on 17 July, Zen Master Dae Bong, Zen Master Dae Kwan & Myong Hae Sunim JDPSN shared the teachings and life of Zen Master Su Bong.
