成唯識論述記 10.91

10.91

述曰：餘義無諍，唯「願」不以惠為自性，即以欲、勝解及信三為性，「願」以三法為自性故。說是後得智者，唯後得智中起故。初五度則不然，《攝大乘》等說：或欲、勝解為願體；或信、勝解為願。今合言之，故云：以三法為體。

The Commentary states: For the other meanings there is no dispute; only "vow" does not take wisdom as its self-nature, but rather takes desire (chanda), resolve (adhimokṣa), and faith (śraddhā), these three, as its nature, because a "vow" takes these three phenomena as its self-nature. Stating that it is subsequent-attainment wisdom is because it arises only within subsequent-attainment wisdom. The first five perfections, however, are not like this. The Mahāyānasaṃgraha and other texts state: either desire and resolve are the nature of the vow; or faith and resolve are the vow. Here they are combined, hence it says: it takes three phenomena as its nature.
