Havredal Zendo - Cho-An is a Buddhist temple, formerly in the Rinzai Zen tradition, founded by Choan Denko Møller (John Mortensen). Denko Møller first became interested in Zen Buddhism in the late sixties in Denmark. He went to Ryutaku-ji in Japan, where he met Soen Nakagawa. Later he became a student of Soen's successor, Eido Shimano. Denko was ordained as a Rinzai Zen Buddhist priest on July 4, 1980 and received Dharma transmission from Eido in 2002. Denko later broke with Eido Shimano and became an independent teacher. Denko is a member of the American Zen Teachers Association.
