Niu-T’ou Fa-yung (594-657) asks the Patriarch, the Chan master Tao-hsin: “As you do not permit contemplation, what do you do when mental attitude emerges?”
Tao-hsin: “The origin of mental attitude is neither good nor bad; its emergence is due to your mind. If your mind were free from formulation or conception, how could illusions occur? When illusions do not occur, the real mind will be free to be aware of everything. You just follow the mind as it is. Do not look for ways to deal with it. This is called the ever abiding essence of things [dharmakaya]” (The Original Teaching of Chan Buddhism, trans. Chang Chung-Yuan, pp. 19-20).
You just follow the mind as it is. Do not look for ways to deal with it. No touching. No poking. No cajoling. No manipulating. No yes this or no that. Just keen observant accepting of whatever is arising.
