As a young monk, Shunryu Suzuki met the revered Oka Sotan (on the right) when Oka Sotan visited Zounin, Gyokujun So-on, Shunryu's master's temple. Later Shunryu praised Oka Sotan's teaching as the root teaching for him and many of the senior and contemporary priests that he respected. His master So-on had studied with Sotan and Sotan gave transmission to his teacher Kishizawa and the famous Kodo Sawaki (on the left in the photo).
