金剛般若波羅蜜經註解 1.208

1.208

所得者，忘情而證也。無實者，非有為相也；無虛者，是真如體也。然此真如非別有法，即一切色等諸法，離性、離相，名真如體，唯佛與佛乃能證此。故一切法皆是佛法，真如之體雖不離於諸法，然亦不可取著，故云：「即非一切法，是名一切法。」

"Attained" means realizing while forgetting sentiment. "Neither truth" means not possessing conditioned marks; "nor falsehood" means being the substance of tathatā. Yet this tathatā is not a separate dharma; it is identical to all form and other dharmas, free from nature and free from marks, named the substance of tathatā, which only a Buddha together with a Buddha can realize. Therefore all dharmas are Buddha Dharmas. Although the substance of tathatā is not apart from all dharmas, it also cannot be grasped; hence it says: "are not all dharmas; therefore they are named all dharmas."
