Sokuzan talks about several lines in Genjokoan (Actualizing the Fundamental Point) from Dogen’s Shobogenzo: “To study the way of enlightenment is to study the self. To study the self is to forget the self. To forget the self is to be actualized by myriad things. When actualized by myriad things, your body and mind as well as the bodies and minds of others drop away. No trace of enlightenment remains, and this no trace continues endlessly. “ (Translation edited by Kazuaki Tanahashi)
