俱舍論疏 20.158

20.158

「論曰至加行三力」，明三因也。將起欲貪纏時，由未斷貪得為因力，即由得力令貪生故，如《正理》說。又云「三緣故說未斷未遍知，謂得未斷故，對治未生故，未遍知境故，順欲貪境現在前故。是境界力，緣彼非理作意起故，是加行也。」

Regarding the passage in the treatise from "It is said in the treatise" to "the three powers of preparatory application": This explains the three causes. When the entrapment of sensual desire is about to arise, the possession of unabandoned desire serves as the power of the cause; that is, the power of possession causes desire to arise, as explained in the Nyāyānusāra. It also says: "Through three conditions it is said to be unabandoned and not fully known: namely, because possession is not abandoned, because the antidote has not arisen, and because the objective field is not fully known, an objective field conducive to sensual desire is present before oneself. This is the power of the objective field. Because improper attention arises with that as its object, it is preparatory application."
