大乘起信論裂網疏 3.59

3.59

This follows on the above text. Merely because the unshared ignorance of the seventh does not truly know the oneness of the true dharma, it inwardly takes the eighth as an object and gives rise to the two grasps at self, and outwardly serves as the basis for the six, causing them to give rise to false thoughts; thus there are all the dharmas of the world, such as the dependent [environment] and the primary [retribution of sentient beings]. All these dharmas are transformed by the minds of the eight consciousnesses, and take the minds of the eight consciousnesses as their intrinsic nature. If one is separated from the eight consciousness-minds that are capable of transforming, what transformed sense-objects of the six dusts could be apprehended? This being so, all dharmas are completely inseparable from the eighth, the fundamental consciousness; hence it is said that they 'have the mind as primary'. They are all illusorily manifested from the ignorance of the seventh; hence it is said that they 'arise from false thought'. When the eighth discriminates the three categories of objects with real nature, these are still the perceived part transformed by the eighth; when the seventh discriminates the false self and dharmas, these are still the perceived part transformed by the seventh; when the sixth discriminates all dharmas, these are still the perceived part transformed by the sixth; when the first five discriminate the real-nature objects of the five dusts, these are still the perceived parts transformed by the first five. Hence it is said that 'whatever is discriminated is only the discrimination of one's own mind'. For example, if someone opens their eyes wide seeking to find their own eyes, they will never be able to see them; the mind is also like this. Hence it is said that 'the mind does not see the mind'. However, although the eye does not see itself, there are still other people who can see its eye; whereas the mind does not see the mind, and there can definitely be no other person who can see its mind. Hence it is said that 'no mark can be apprehended'.
