成唯識論述記 6.96

6.96

The Commentary states: The mind focuses exclusively on a single object; cognizing in reliance on the teaching, it realizes and understands the intentional object, and the mind then becomes bright and pure. Due to this, anāsrava wisdom arises, capable of knowing the characteristics of virtue, fault, and so forth in the intentional object. In terms of the four requisites of the Dharma, concentration can generate wisdom, but it does not necessarily have to be so in every instance.
