成唯識論述記 6.430

6.430

述曰：下文有五：一、破前；二、釋難；三、顯正；四、引證；五、解疑。此初也。前義不然，汝言推事未決有三性心，汝言彼善心中無信者，應非是善；無淨信故；如染、無記心。染等者，等取無記也。又云：善心定有信起；善心攝故；如定時善心。

The Commentary states: The following text has five parts: first, refuting the previous view; second, resolving objections; third, revealing the correct view; fourth, citing proof; fifth, resolving doubts. This is the first. The previous view is incorrect. You say that when investigating facts without decision, there are minds of the three natures. If you say that in that wholesome mind there is no faith, then it should not be wholesome, because it lacks pure faith, just like a defiled or indeterminate mind. "Defiled and so forth" includes indeterminate by "and so forth". Furthermore: A wholesome mind definitely has faith arising, because it is subsumed under wholesome mind, just like a wholesome mind at the time of concentration.
