俱舍論疏 27.102

27.102

論「理實一切至能為加行」，論主述正釋也，以佛語中具有四故。《婆沙》一百八十，評家云「如是說者，四無礙解皆以習佛語為加行。如於一伽陀中，應如是說彼名，習如是說名，是法無礙解加行。應如是解彼義，習如是解義，是義無礙解加行。應如是訓彼詞習，如是訓詞，是詞無礙解加行。應如是無滯說，習如是無滯說，是辨無礙解加行。皆以習佛語為加行（已上論文）。」

The Śāstra states: "In actual truth, all up to can serve as preparatory application," in which the author of the treatise states the correct explanation, because the words of the Buddha contain all four. In the Vibhāṣā, scroll 180, the evaluators say: "The correct explanation is this: all four unobstructed understandings take practising the words of the Buddha as their preparatory application. Just as in a single gāthā, one should state its names in such a way, and practising stating the names in such a way is the preparatory application for the unobstructed understanding of phenomena. One should understand its meaning in such a way, and practising understanding the meaning in such a way is the preparatory application for the unobstructed understanding of meaning. One should gloss its terms in such a way, and practising glossing terms in such a way is the preparatory application for the unobstructed understanding of etymology. One should speak without impediment in such a way, and practising speaking without impediment in such a way is the preparatory application for the unobstructed understanding of eloquence. All take practising the words of the Buddha as their preparatory application." (End of śāstra citation.)
