俱舍論記 24.99

24.99

「不爾未如實至重說學言」者，釋。不爾，異生雖學戒等，未得無漏慧如實見知四諦理故，彼容後時退失正學，入諸外道作邪學故，故不於彼立有學名。諸有學已能如實見諦，正學無退得有學名。由此善逝為顯定義，於有學者再說學言。如契經中佛告憺怕：「學所應學無漏正法。學所應學無漏正法，我唯說此名有學者。」論主釋經，為令了知學正所學無漏戒等無有退失名有學者，故薄伽梵重說學言。聖雖有退，必無退盡作邪學理，故名不退。

[The phrase] "Not so; because they have not as it truly is […] repeats the word 'training'" is the explanation. It is not so. Although ordinary persons train in śīla and so forth, because they have not yet attained uncontaminated wisdom to see and know the principle of the four truths as it truly is, it is possible that at a later time they may fall away from proper training and enter non-Buddhist traditions to perform false training; therefore, the name 'one in training' is not established for them. All those in training have already been able to see the truths as they truly are, and their proper training is without regression, so they obtain the name 'those in training'. Therefore, in order to show the definitive meaning, the Sugata repeated the word 'training' with respect to those in training. As in a sūtra where the Buddha addressed Śānta: "One trains in the uncontaminated true Dharma that ought to be trained in. One trains in the uncontaminated true Dharma that ought to be trained in; I declare only such a person to be named 'one in training'." The author of the treatise explains the sūtra: in order to make it understood that one who trains in what is properly trained in—uncontaminated śīla and so forth—without regression is called one in training, the Bhagavān repeated the word 'training'. Although a noble one may have retrogression, there is definitely no principle of retrogressing completely to perform false training; hence it is called non-retrogression.
