俱舍論疏 23.101

23.101

論「言一坐者至乃至菩提」，此敘二說不起坐也。一說從煖位、一說不淨觀。《正理論》云「依第四禪，從身念處至盡、無生，唯於一坐能次第起。故麟角喻及佛種姓，煖等善根皆不可轉。」餘文可解。准之，一坐已後說不可轉，與《婆沙》不同，是論意別。或是《婆沙》前文以是利根一義故不轉，此中兼一坐二義不轉，非是欲許前位轉也。

On the Śāstra's statement: "Speaking of 'a single session' ... up to bodhi": this recounts the two explanations of not rising from the seat. One explanation is from the stage of warmth; one explanation is from the meditation on the repulsive. The *Nyāyānusāra* says: "Relying on the fourth dhyāna, from mindfulness of the body up to [the knowledge of] destruction and non-arising, one can arise successively in only a single session. Therefore, for the rhinoceros-horn-like and the Buddha disposition, the roots of goodness such as warmth cannot be converted at all." The rest of the text can be understood. Based on this, stating that after a single session they cannot be converted differs from the *Vibhāṣā*; this is a difference in the treatise's intention. Or it may be that the earlier text of the *Vibhāṣā* maintains non-conversion by the single reason of sharp faculties, whereas here it combines the two reasons of sharp faculties and a single session for non-conversion, not that it intends to permit conversion in the earlier stages.
