大般涅槃經義記 5.298

5.298

上來第一以說不定類四無量，自下第二化人不定類四無量。於中先明化人不定，「應如」已下類四無量。前中，初以四句廣辯，初三身化，後一口化。「如來如是於無量」下結成非虛，先明非虛，「如來雖處眾惡」已下釋成非虛，處惡不染，故無妄罪。

The preceding was the first part, which by analogy with the indefiniteness of preaching illustrated the four immeasurables; from here below is the second part, which by analogy with the indefiniteness of the persons transformed illustrates the four immeasurables. Herein, it first clarifies the indefiniteness of the persons transformed, and from "should be like" downward it draws the analogy to the four immeasurables. In the former part, it first explains extensively with four clauses: the first three are physical transformations, and the last is oral transformation. From "The Tathāgata thus in immeasurable" downward concludes that this is not false; first it clarifies non-falsity, and from "Although the Tathāgata abides among various evils" downward explains and establishes non-falsity: abiding among evils without defilement, he therefore has no offense of falsity.
