大方廣佛華嚴經隨疏演義鈔 4.31

4.31

疏「五真應無礙應即同法一味平等故」者，釋迦、遮那無二佛故，吾今此身即法身故。第五經云「真如平等無相身，離垢光明淨法身，智慧寂靜身無量，普應十方而演法。」又云「如來真身本無二，應物分形滿世間。」〈光明覺品〉云「如來非以相為體，但是無相寂滅法，身相威儀悉具足，世間隨樂皆得見」等。

Regarding the commentary's statement, "Fifth, unimpededness between true and responsive [bodies], because the responsive is identical to the Dharma in single-flavor equality": this is because Śākyamuni and Vairocana are not two Buddhas, and because this present body of mine is itself the dharmakāya. The fifth fascicle states: "The signless body equal to tathatā, / the pure dharmakāya of light free from defilement, / the quiescent body of wisdom is immeasurable; / responding universally to the ten directions, it expounds the Dharma." It also states: "The true body of the Tathāgata is fundamentally non-dual; / responding to things, it divides forms to fill the world." The Chapter on Awakening through Light states: "The Tathāgata does not take characteristics as essence, / but is only the signless, quiescent Dharma; / the bodily marks and deportment are all complete, / and the world, according to its inclinations, is permitted to see them," and so forth.
