起信論疏筆削記 15.13

15.13

二、釋見麁所以。疏　迷唯心者，佛從心內現，反見心外來，不知唯識，故云迷心。論　取色下，迷境也。由迷唯識現取，遂見心外實有境界，不知即空，故取分齊也。不能盡知者，不知色如其心，無分齊故，但見分齊，故不盡也。

2. Explaining the reason why they see coarsely.
[Regarding the text of the] commentary: As for "deluded about mind-only", the Buddha manifests from within the mind, yet they conversely see him coming from outside the mind; not knowing mind-only, it is therefore said to be "deluded about the mind".
[Regarding the text of the] śāstra: From "grasping at form..." downward, it is delusion regarding the object. Due to being deluded about mind-only manifesting and grasping, they consequently see real objects outside the mind, unaware that they are identical to emptiness, and therefore grasp at boundaries. As for "unable to fully know", they do not know that form is like its mind, having no boundaries; seeing only boundaries, they therefore do not fully [know it].
