唯識二十論述記 1.274

1.274

述曰：二乘、異生諸愚夫等，起計所執，自性諸法，差別諸法，以為實有，即是諸法體及用也，令知此所執性，體、用都無，名入法無我，非知真俗、凡聖等境亦都無故，名入法無我。

The Commentary says: Foolish persons such as followers of the two vehicles and ordinary worldlings give rise to conceptualizing grasps, taking phenomena as intrinsic natures and phenomena as distinctions to be truly existent—namely, the substances and functions of phenomena. Causing them to know that this grasped nature is completely devoid of substance and function is called entering the selflessness of phenomena; it is not called entering the selflessness of phenomena because of knowing that objects such as ultimate and conventional, or ordinary and noble, are also completely non-existent.
