To sign off that a student has arrived at the state of wisdom-insight, kensho-satori or Buddha Mind, the Zen Teacher looks for signs that signify that the student has arrived at and dwells in one, more or all of the mind-states below: (1) A sense of the non-existence of self (2) A sense of realization of non-dual reality (3) A sense of liberation, freedom and ease (4) A sense of a direct, non-intellectual perception of reality and a deep insight into the nature of things (5) An apprehension of the ultimate unchanging reality of emptiness: Nothing comes into existence or disappears
