佛祖統紀 3.58

3.58

然初頓未必純教法身菩薩。亦有凡夫大根性人。此有兩義。若當體圓頓得悟者。即破無明入圓初住。此是醍醐。若初心之人。雖聞大教始入十信。最是初味。名之為乳。呼為乳者。意不在淡。以初故本故（圓教內凡六根清淨。即是十信。初信斷見。二信至七信斷思。八信至十信斷界內外塵沙惑。以未破無明。故但名乳）若小根性人。大教擬小如聾如瘂。小機未轉全生如乳（妙玄十）。

However, the initial sudden teaching does not necessarily teach only Dharma-body bodhisattvas; there are also ordinary beings of great capacity. Here there are two meanings: If someone directly awakens to the round and sudden principle itself, they immediately break through ignorance and enter the first abode of the round teaching; this is clarified butter. If they are beginners, although hearing the great teaching, they only enter the ten faiths; this is the earliest flavor, named milk. It is called milk not because of being bland, but because it is the beginning and the root. (Internal ordinary beings of the round teaching with purity of the six faculties are precisely the ten faiths. The first faith severs view-delusion; the second to seventh faiths sever thought-delusion; the eighth to tenth faiths sever dust-and-sand delusions within and beyond the realms. Because they have not yet broken through ignorance, it is merely called milk.) If they are people of small capacity, when the great teaching is directed toward the small, they are like the deaf and mute; their small capacity has not been transformed, remaining completely raw like milk (Miaoxuan, fascicle 10).
