大乘義章 1.131

1.131

言法性者，廢詮論理，理是一味。一味之理，是法體性，故云法性。是以論言「總為一空，名為法性。」言實際者，論自釋言「如及法性名之為實，證處名際。」言就實性有無分者，如經中說「如來藏中具過恒沙一切佛法，不離不脫、不斷不異。是諸佛法同一體性，互相集成，無有一法別守自性。雖無一性，而無不性。」無有一性，即是如義。而無不性，即是法性。言實際者，彼如法性即是其實，證處名際（此二門竟）。

Regarding dharmatā: setting aside verbal expressions to discuss the principle, the principle is of a single flavor. The principle of a single flavor is the essential nature of dharmas; hence it is called dharmatā. Therefore the treatise says: 'Synthesized into a single emptiness, it is called dharmatā.' Regarding bhūtakoṭi, the treatise itself explains: 'Tathatā and dharmatā are called reality, and the locus of realization is called the limit.' Regarding distinguishing them in terms of the existence and non-existence of the real nature, as stated in a sūtra: 'Within the tathāgatagarbha are fully possessed all the Buddha-dharmas exceeding the sands of the Ganges, neither detached nor separated, neither cut off nor different. These Buddha-dharmas are of one same substance and nature, mutually constituting one another, without a single dharma independently maintaining its own nature. Although there is not a single nature, there is no nature that is not present.' Not having a single nature is precisely the meaning of tathatā. Yet with no nature not present, that is precisely dharmatā. Regarding bhūtakoṭi, that tathatā and dharmatā are precisely its reality, and the locus of realization is called the limit. (This concludes the second portal.)
