摩訶止觀 5.142

5.142

己說前人根性利鈍竟，云何安心？師應問言：「汝於定慧，為志何等？」其人若言：「我聞佛說：『善知識者，如月形光，漸漸圓著；又如梯隥，漸漸增高。巧說轉人心，得道全因緣；志欣渴飲，如犢逐母。』」當知是則信行人也。若言：「我聞佛說：『明鏡體若不動，色像分明；淨水無波，魚石自現。欣捨惡覺，如棄重檐。』」當知是則法行人也。既知根性，於一人所，八番安心。

Having finished explaining the sharpness and dullness of the other person's faculties, how does one settle the mind? The teacher should ask: 'Regarding concentration and wisdom, toward which is your aspiration set?' If the person says: 'I have heard the Buddha say: "A good friend is like the form and light of the moon, gradually growing round and full; again, like steps of a ladder, gradually rising higher. Skillful speech turns people's minds; it is the complete causal condition for attaining the Path. With longing aspiration, one thirsts to drink, like a calf following its mother."' One should know that this is a follower of faith. If the person says: 'I have heard the Buddha say: "If the body of a clear mirror does not move, colors and images are distinctly clear; if clean water has no waves, fish and stones naturally appear. One delights in casting off bad awareness, like discarding a heavy burden."' One should know that this is a follower of the Dharma. Once the faculties are known, in the case of a single person, there are eight ways of settling the mind.
