大般涅槃經義記 5.145

5.145

In the second question, Kāśyapa says further, "If such dharmas are within the four truths, why did the Tathāgata proclaim that they were not spoken?" re-challenging his past words. Below, the Buddha explains for him: "Although they again enter therein, they are still not called spoken," briefly answering his question: because they enter generally, they are individually not called spoken. Below he explains it extensively, first questioning why, and below contrasting and explaining. First dividing into two wisdoms, he first introduces and next enumerates them. Below, discussed in terms of persons, there are three wisdoms in total: lower wisdom resides in ordinary persons; they do not know the truths, so it was not spoken [to them]. Below, explaining in terms of the truths: what is known by intermediate wisdom is the truth with activity, also called having measure; what is known by superior wisdom is the truth without activity, also called measureless.
