大乘起信論義記 3.56

3.56

Below, in explaining the hindrance to cognition, 'because all dharmas are constantly tranquil and without marks of arising' adduces the dharmatā obscured by avidyā. 'Avidyā non-enlightenment falsely conflicts with dharmas' directly shows how avidyā conflicts with the aforementioned dharmatā: because it fails to comprehend that things are tranquil like reality, and falsely has arising and ceasing, it runs contrary to dharmas. 'Cannot... know them in their manifold ways': because it is internally deluded about the true principle and sees external dust outside of consciousness, it cannot accord with the realms of conventional reality and know them in their manifold ways. This directly explains the meaning of obstructing the cognition of conventional reality. The explanation of the causes and conditions of arising and ceasing is now concluded.
