大方廣佛華嚴經隨疏演義鈔 23.59

23.59

疏「體不出五」者，即《攝論》、《佛地論》皆言五法攝大覺性，謂一真法界、四智菩提，則一是理而非是智。今清淨智即一真法界，清淨智即本來智性。《金剛頂瑜伽》說有五智，初法界清淨智即一真法界故。

Regarding the commentary's statement, "Its essence does not go beyond five": this is because both the Mahāyānasaṃgraha and the Buddhabhūmi-śāstra state that five dharmas subsume the nature of great awakening—namely, the one true dharmadhātu and the four wisdoms of bodhi. Thus one is principle and not wisdom. Now, the pure wisdom is precisely the one true dharmadhātu; pure wisdom is the original nature of wisdom. The Vajraśekhara Yoga speaks of five wisdoms, because the first, the dharmadhātu-viśuddhi-jñāna, is precisely the one true dharmadhātu.
