俱舍論疏 25.183

25.183

論「由所信別至故唯有二」，明信三不同。分信為三，實體唯信，戒復為一，故體唯二。

[On the passage of] the śāstra, "Due to the differences in what is believed in... therefore there are only two," this clarifies that faith is threefold and different. Dividing faith into three, its real essence is only faith; morality makes another one, so their real essences are only two.
