7.97

上來第二教生解心，自下第三明由前二便能自知是波羅蜜非波羅蜜，乃至能知涅槃大小。

The above was the second part, teaching the generation of the mind of understanding. From here below is the third part, clarifying that through the previous two one is able to know for oneself whether something is a pāramitā or not a pāramitā, and even able to know the great and small of nirvāṇa.
