Mind of Non-Thinking
To cut away this mass of delusion with the sword of prajna-wisdom, so that we may discover the bright mind of the real self, is called the controlling of mind. As the text says, we should not think good or evil, advantage or disadvantage, love or hate. This no mind state where nothing exists is the correct posture of the mind. Dogen Zenji says, "Don't think anything." He recommends controlling the mind, pointing to the real self which is the mind of nonthinking. Since illusion and delusion, like mist, have no substance, they will disappear if we do not focus o n them. http://onedropzen.org/uploads/Yamada_Mumon_Roshi.pdf
