2.63

「所以者何」，此下是第二總釋諸佛二智，此詺舉昔諸佛行釋二智所以，諸佛實智甚深無量者何？復言其智慧門難解難入者何？以佛曾親近百千萬億盡行昔日諸佛之行故，得此二智深妙也。只就此釋中自有三：第一「佛曾親近」以下明行本，第二「盡行諸佛」以下正明行行，第三「名稱普聞」一句結顯。

"Why is this?" From here down is the second [part], generally explaining the two knowledges of the Buddhas. This is designated as citing the past practices of the Buddhas to explain the reasons for the two knowledges. Why is the real knowledge of the Buddhas profoundly deep and immeasurable? And why is it said that the gate to their wisdom is difficult to understand and difficult to enter? Because the Buddha formerly drew close to hundreds of thousands of myriads of koṭis [of Buddhas] and completely carried out the practices of the Buddhas of former days, he attained these two knowledges to be profound and subtle. Within this explanation itself there are three: first, from "The Buddha formerly drew close to" onwards clarifies the root of the practices; second, from "completely carried out [the practices of] the Buddhas" onwards directly clarifies the carrying out of the practices; third, the single phrase "their names are universally heard" concludes and manifests [it].
