俱舍論疏 9.252

9.252

The treatise says: "In this way, the word 'entire' indicates that there are only conditioned formations without a self or what belongs to a self." The words "great mass of suffering" show that suffering has no beginning and no end, hence it is called "great." The word "origination" is to show the arising of the masses of suffering; origination has the sense of arising. This explains the phrase in the sūtra: "the origination of this entire great mass of suffering."
