論。無有自性　釋曰。此則對明性離惑染義。此中應言。若心有動。無有自性。心性無動即是自性清淨心義故。義難知故但舉一句。有義。此說執取計名。以是事識麁分之位取著轉深發業滅苦。是故名為無有自性。有義。此亦通對諸染。若唯二相無自性者。其外染心應有自性。由有妄動成九染相故無自性。心性無動即說自性清淨心義也。

[Treatise:] it has no intrinsic nature; [Commentary:] This contrastively reveals the meaning of the nature being free from the defilement of afflictions. Here it should say: "If the mind has movement, it has no intrinsic nature; the nature of the mind is free from movement, which is the meaning of the intrinsically pure mind." Because the meaning is difficult to know, it only raises one sentence. One opinion holds: this speaks of grasping and attachment to names, because at the stage of the coarse division of phenomenal consciousness, grasping grows ever deeper, initiating karma and producing suffering; therefore it is called "having no intrinsic nature". Another opinion holds: this also generally contrasts with all defilements. If only the two characteristics lacked intrinsic nature, then the other defiled minds outside them would have intrinsic nature. Due to false movement forming the nine defiled characteristics, they lack intrinsic nature; because the nature of the mind is free from movement, it expresses the meaning of the intrinsically pure mind.
