楞伽阿跋多羅寶經註解 4.15

4.15

This is discussed in terms of prajñā relative to the cognitive obstacle (jñeyāvaraṇa). "Jñāna" is prajñā, and "jñeya" (er yan) refers to the cognitive obstacle. By analogy to what preceded, it should properly say: "If they were different, there would be no wisdom apart from obstacles; if they were not different, how could obstacles be wisdom?" Merely saying "neither different nor not different" is an abbreviation of the text. Because prajñā and the cognitive obstacle are neither different nor not different, they are not two and not distinct from the dharmakāya and liberation; hence it again summarizes and applies it universally. Stating "neither permanent nor impermanent" and so forth does not depart from revealing the middle path by negating the two extremes, revealing the one characteristic by negating subject and object, and revealing the transcendence of words by negating the catuṣkoṭi; therefore it is also said to "transcend all measures." "Measures" refers to reckonings and standards.
