大乘起信論義記 3.59

3.59

In the former part, 'the coarse, because it is conjoined with the mind' means that among the six defilements, the former three defilements are conjoined with the mind; their marks are coarse and prominent, and in the sūtras this is called phenomenal arising and ceasing. 'The subtle, because it is unconjoined with the mind' means that the latter three defilements are unconjoined with the mind; lacking the coarse and prominent marks of mind and mental factors, their essence is subtle and flows constantly without interruption, which in the sūtras is called flux arising and ceasing. This relies on the four-fascicle *Laṅkāvatāra*. In the ten-fascicle version it says: 'There are two kinds of cessation of consciousness: first, cessation of marks; second, cessation of continuity. Arising and abiding are also like this.' The sūtras bring out the names without separately showing their marks; therefore the treatise master now relies on the meanings of conjoined and unconjoined to reveal the marks of arising and ceasing of these two kinds of coarse and subtle minds.
