天台八教大意 1.49

1.49

《涅槃》二十七云：「雪山有草名為忍辱，牛若食者即成醍醐。」草喻八正，能修八正即見佛性，此譬圓教不歷四味即成醍醐。

The twenty-seventh fascicle of the *Nirvāṇa Sūtra* states: 'On the Snow Mountains there is a grass named forbearance; if a cow grazes on it, it directly produces ghee.' The grass exemplifies the eightfold noble path; being able to cultivate the eightfold noble path, one directly perceives the buddha-nature. This metaphor corresponds to the perfect teaching directly producing ghee without passing through the four flavors.
