俱舍論疏 23.33

23.33

論「觀苦聖諦至如後當辨」，此列十六行相名也。《正理論》云「然諸煖法雖緣四諦，而從多分說厭行俱，以起彼時蘊想多故。」准此論文，在煖位時偏觀苦、集。

[On] the treatise's: "Contemplating the noble truth of suffering... as will be explained later", this lists the names of the sixteen aspects. The Nyāyānusāra says: "Although all [stages of] Heat take the four truths as objects, they are said to be conjoined mostly with weary practice, because when arising then, ideations of the aggregates are numerous." According to this text, at the stage of Heat one predominantly contemplates suffering and origination.
