佛祖統紀 3.52

3.52

玄文言大機稟教即破無明行如醍醐者（文）此指華嚴高山王機也。涅槃言從牛出乳者。此約一化指聲聞聾瘂也。故玄文云三教分別。即名頓教。亦即醍醐五味分別即名乳教。今言從牛出乳者即初味也。

When the *Xuanwen* says that those of great capacity receive the teaching and immediately destroy ignorance, their practice being like clarified butter (text), this refers to the capacities of the kingly high mountains of the *Huayan*. When the *Nirvāṇa* says that from cows comes milk, this is spoken in terms of a single lifetime's teaching, pointing to the voice-hearers being deaf and mute. Therefore, the *Xuanwen* says that distinguishing by the three teachings is called the Sudden Teaching, which is also clarified butter; distinguishing by the five flavors is called the milk teaching. Now, stating that from cows comes milk refers to the first flavor.
