大乘起信論義記別記 1.16

1.16

「根本智」有二類：一、修起如理智；二、真如本覺智。世間智亦二：一、修生如量智；二、本覺隨染智。以染心睻動，違不動平等本覺之智，故名「煩惱礙」。又無明不了即動是靜故，是以動中不能差別而知，「智礙」也。

“Fundamental wisdom” has two classes: first, wisdom in accordance with principle produced through practice; second, the original enlightenment wisdom of tathatā. Mundane wisdom also has two: first, wisdom in accordance with measure produced through practice; second, the wisdom of original enlightenment conforming to defilement. Because the defiled mind is agitated and moving, conflicting with the unmoving, impartial wisdom of original enlightenment, it is called the “hindrance of affliction.” Furthermore, because avidyā fails to comprehend that movement is itself stillness, one cannot know distinctively amidst movement; this is the “hindrance to wisdom.”
