瑜伽師地論略纂 4.141

4.141

16. "One is the cause of the cognitive obscuration (jñeyāvaraṇa)": earlier, it was explained that afflictions, karma, and suffering subsume the twelve constituents, having fully analysed that all twelve are the affliction obscuration (kleśāvaraṇa). The Buddhabhūmi-śāstra states: "Whether the one hundred and twenty-eight afflictions and so forth, or the karma initiated, or the fruit obtained, all are the affliction obscuration." Therefore this is not asked here; it asks solely about the cognitive obscuration, namely ignorance. Ignorance serves as the cause for attachment to dharmas and indeterminate prajñā; hence it is called the cause of the cognitive obscuration. In true principle, for both the cognitive obscuration and the affliction obscuration, ignorance is the cause. The Weishi says: "Because that actually uses this as its support." Now, speaking of the ignorance that initiates karma, because bewilderment regarding principle is prominent, and because it is co-existent with it, acting as the cause of the cognitive obscuration is also not contradictory. Furthermore, because this ignorance initiates karma and brings about rebirth, subsequent cognitive obscurations increase and arise successively; ignorance is the root, so it is uniquely stated to be the cause.
