In this study session, Zuisei explores Koso Uchiyama’s Opening the Hand of Thought, a contemporary Zen text that speaks about the importance of zazen and letting go of thoughts in order to see the nature of the self. In the words of Uchiyama Roshi: You are within me. I'm just facing myself. In other words, you exist within myself, and it is to that you that I direct myself. That is what "vow" is.
