大方廣圓覺修多羅了義經略疏 1.206

1.206

藏即寶性法界藏，起信心真如，是諸佛、眾生之本源，神通光明之性體。塵沙德用並蘊其中，百千通光皆從斯起，故云藏也，亦名法性土，亦名常寂光土。息諸分別，智與理冥，名為入矣。然諸佛有常光、放光。若約常光，光即是藏，謂心性本明，迷之似闇。妄想既盡，顯煥無涯。故論云：「心性不起，即是大智慧光明遍照法界。」若約所放光及所起通，即神通光明之藏。

The store is the jewel-nature dharmadhātu-garbha, the tathatā of the *Awakening of Faith*, which is the fundamental source of all buddhas and sentient beings, and the essential nature of supernormal powers and radiance. The virtuous functions numerous as dust and sand are all contained within it, and the hundreds of thousands of supernormal powers and radiances all arise from this; hence it is called a store. It is also called the dharmatā land, and also the land of eternally quiescent light. Putting an end to all conceptual distinctions, wisdom merging with principle is called "entering". Now, all buddhas possess constant light and emitted light. In terms of constant light, light is itself the store; that is, the mental nature is fundamentally luminous, but when deluded it appears as darkness. Once vain thoughts are exhausted, it shines forth boundlessly. Thus the treatise says: "When the mental nature does not arise, it is the great wisdom radiance universally illuminating the dharmadhātu." In terms of the light emitted and the supernormal powers manifested, it is the store of supernormal powers and light.
