大般涅槃經義記 3.321

3.321

就下教入祕藏之中，先應解釋三歸之義，義如別章。然後釋文。文中有四：初有半偈總勸分別、次有半偈正教祕藏、次一偈半彰益勸觀、末後一偈結嘆顯勝。

In the instruction below on entering the secret treasury, one should first explain the meaning of the three refuges, the meaning of which is as in the separate chapter; thereafter one explains the text. In the text there are four parts: first, a half-verse broadly encourages differentiation; next, a half-verse directly instructs on the secret treasury; next, one and a half verses reveal the benefit and encourage contemplation; the final verse concludes with praise, revealing its excellence.
