18.237

基云：觀察清淨因故者，即下言緣此名能知諸人無我故，顯彼理故名清因。觀自相者，即下言緣二種名故我相不可得，即是二執相分也。今知其事，觀察染因者，即下言不善了知，此名即染污生起故也。即是彼見分生起故一切法生也。

Ji says: "Observing the cause of purity" refers to what is stated below: taking this name as object, one can know the selflessness of persons; because it reveals that principle, it is called the cause of purity. "Observing self-characteristics" refers to what is stated below: taking the two kinds of names as object, the characteristic of a self is unfindable; this is the object-aspect (nimittabhāga) of the two attachments. Now one knows that fact. "Observing the cause of defilement" refers to what is stated below: through not properly knowing it, this name immediately generates defilement; that is, because of the arising of that vision-aspect (darśanabhāga), all phenomena arise.
