起信論註 1.20

1.20

論亦無有相可取以離念境界唯證相應故　（述曰。此釋外疑也。恐□不空疑存有相故。念遮云。雖曰不空無有相而可執。取下釋所以非妄念。所行境界唯是證智所體會故。即顯真心不空而空也）。

Treatise: There are also no marks that can be apprehended, because it is a realm free of thought, only associated with realization. (Commentary: This resolves an outside doubt. Fearing that [by hearing of] non-emptiness one might suspect that marks exist, it negates this with thought, saying: although it is called non-empty, there are no marks that can be grasped. Below it explains the reason: it is not a realm navigated by deluded thought, but is only realized by realized cognition. That is, it reveals that the true mind is non-empty yet empty.)
