俱舍論疏 26.181

26.181

論「智增故至為其自性」，辨體也。古德釋：俗智是同觀修，以苦見道同觀諦故。見道觀諦令彼觀諦智增，遂起於得，故名同觀修。准此，於見道中有同類智見道為觀諦理，而不為斷惑。又有漏智無別斷見惑。以是義故，故非同治。

The passage of the śāstra from “Because knowledge is augmented” up to “forms its essential nature” analyzes the intrinsic nature. Ancient masters explained: Conventional knowledge is cultivated through identical contemplation (tongguan xiu), because during the path of seeing of suffering, there is identical contemplation of the truth. When the path of seeing contemplates the truth, it causes that knowledge which contemplates the truth to be augmented, and thereupon an acquisition arises; hence it is called “cultivation through identical contemplation.” According to this, within the path of seeing, knowledge of the same class (sabhāga-jñāna) within the path of seeing contemplates the principle of the truths, but does not serve to abandon defilements. Moreover, impure knowledge does not separately abandon defilements to be abandoned by seeing. Because of this meaning, it is not an identical counteragent (tongzhi).
