大乘起信論義記 2.38

2.38

初中言以一切言說假名無實者，明言教非實，不可如言取也。但隨妄念等者，釋成無實所以也，恐諸凡愚聞上真如名，則謂論主自語相違：上文既云離名字相，何故復立此真如名？故今釋遣假名非實，不相違也。亦言無相者，遣於相也，良以名依相立，俱是遍計所緣故。《楞伽》云「相名常相隨，而生諸妄想。」故今雙遣也。

In the first part, "Because all verbal expressions are provisional designations without reality" clarifies that verbal teachings are not real and cannot be grasped according to the words. "Merely follow delusional thoughts..." and so forth explains the reason why they are without reality. Fearing that ordinary fools, hearing the name "tathatā" above, would claim the treatise master is contradicting his own words—saying, "Since the preceding text says it is free from the marks of designations, why does he again establish this name 'tathatā'?"—he now explains and dispels [this doubt by showing that] provisional designations are unreal, and so there is no contradiction. Saying "also without any mark" eliminates marks, because names are established based on marks and both are cognitive objects of universal conceptualization. The Laṅkāvatārasūtra says, "Marks and names constantly accompany each other, giving rise to all delusional conceptualizations." Therefore, both are now eliminated.
