俱舍論疏 20.143

20.143

論「應觀此識至皆能緣樂根」，將釋隨增，先須知單緣識，十六法中通幾法。應知通十二，謂欲界四，除見滅斷。此由樂根通有漏，無漏，有漏樂根五識相應，此是欲苦、集諦攝故，通苦、集所斷識緣。樂修道斷故，通修斷意識緣，依第三禪法智品道，道諦攝故。欲界見道斷無漏緣隨眠緣。滅諦非樂根，及見滅所斷中惑不與樂根相應，故見滅所斷不能緣樂根。由斯欲界唯四部也。色界五部皆能緣樂根，樂根通五部故，五部皆能緣也。無色界二，即見道諦及修所斷。見道諦者，謂無漏緣惑能緣。依第三禪類智品道修所斷者，謂有漏善心能緣無漏樂根，即無我觀等。無漏第十二者，通緣三諦樂根故。

The Śāstra says: "One should examine this consciousness […] all can take the faculty of pleasure as an object." About to explain the increase, one must first know how many phenomena among the sixteen categories the consciousness taking an object directly applies to. One should know that it applies to twelve: namely, four in the desire realm, excluding those abandoned by seeing cessation. This is because the faculty of pleasure applies to both the contaminated and the uncontaminated: the contaminated faculty of pleasure is associated with the five consciousnesses, and because it is subsumed under the truths of suffering and origination of the desire realm, it can be taken as an object by consciousnesses abandoned by seeing suffering and origination. Because pleasure is abandoned by the path of cultivation, it can be taken as an object by the mental consciousness abandoned by cultivation. And because the path belonging to dharma-knowledge based on the third dhyāna is subsumed under the truth of the path, it is taken as an object by anuśayas of the desire realm abandoned by the path that take the uncontaminated as objects. The truth of cessation is not the faculty of pleasure, and the defilements among those abandoned by seeing cessation are not associated with the faculty of pleasure, so those abandoned by seeing cessation cannot take the faculty of pleasure as an object. Hence, there are only four categories in the desire realm. All five categories of the form realm can take the faculty of pleasure as an object; because the faculty of pleasure applies to all five categories, all five categories can take it as an object. In the formless realm there are two, namely, those abandoned by seeing the truth of the path and by cultivation. Those abandoned by seeing the truth of the path refers to defilements that take the uncontaminated as an object, which can take it as an object; those abandoned by cultivation refers to the path belonging to subsequent knowledge based on the third dhyāna, namely, wholesome contaminated minds that can take the uncontaminated faculty of pleasure as an object, such as the contemplation of nonself and so forth. The uncontaminated is the twelfth, because it generally takes the faculty of pleasure of the three truths as an object.
