測述三藏言：於三法上假立願故，以三法為體，雖攝論等明十度中願是後智，不應以慧為體，所以爾者？是通體故。以對法云：一切功德皆以定慧為體，此則通體，不可則依彼文云：慈悲喜捨等以慧為體，此亦如是。基云：若剋法即欲信為體。

Ce related the words of the Tripiṭaka Master [Xuanzang]: Because the vow is nominally posited upon three dharmas, it takes the three dharmas as its substance. Although the Mahāyānasaṃgraha and other texts clarify that the vow among the ten perfections is subsequent wisdom, it should not take prajñā as its [exclusive] substance. Why is that? Because it is a common substance. For the Abhidharma says that all merits take concentration and wisdom as their substance; this, then, is a common substance. One cannot simply rely on that text and say that loving-kindness, compassion, sympathetic joy, and equanimity take prajñā as their substance; this is also like that. Ji says: If defined strictly according to the dharma, it takes desire and faith as its substance.
