Korea has a very deep rooted shamanistic tree, I want to visit these temples someday. My Korean Buddhist teacher I met him back in the early 90s, he took care of a Korean temple in Gresham Oregon belongs to the Jogye Order. He taught me all about Karma using the history between the Japanese Buddhist taking over the Korean Buddhist monastic system. The Korean Buddhist finally kicked the Japanese monks out of their temples (Japanese Monks can Marry and forced the Korean Monks to Marry) using thugs who stayed on, being a monk was a cushy job and pretended to be monks, totally corrupting the Korean Monastic system.
