摩訶止觀 1.24

1.24

《大經》云：「從牛出乳，……乃至醍醐。」此證漸也。又云：「置毒乳中，乳即殺人，乃至置毒醍醐，醍醐殺人。」此證不定也。又云：「雪山有草名曰忍辱，牛若食者即得醍醐。」此證頓也。

The Mahāparinirvāṇa-sūtra says: "From the cow comes milk, … and so forth up to clarified ghee." This attests to the gradual. It also says: "If poison is placed in milk, the milk kills people, … and so forth up to if poison is placed in clarified ghee, the clarified ghee kills people." This attests to the indeterminate. It also says: "In the Snowy Mountains there is a grass called 'endurance' (kṣānti); if a cow eats it, clarified ghee is produced immediately." This attests to the sudden.
