金剛經纂要刊定記 2.51

2.51

Namely, after twelve years, the teachings of the various sections of prajñā were expounded to express and reveal wondrous wisdom. Wondrous wisdom is the sixth, prajñāpāramitā. Because the dharmakāya is the wondrous principle of tathatā, originally unarisen and unceasing, yet covered by afflictions, it is called the tathāgatagarbha. If wondrous wisdom illuminates and shatters afflictions, the true principle becomes manifest and constitutes the great dharmakāya; therefore, wondrous wisdom is said to be the cause of the dharmakāya.
