成唯識論演祕 4.91

4.91

The exposition states: The retribution-consciousness is the subtle mental consciousness; the discernible consciousness is the coarse mental consciousness. They would have to operate simultaneously in one body, but this should not be accepted, because it contradicts the sūtras. As the verse states: 'There is no place, no possibility, / Not earlier, not later, / In the same body and of the same category, / For two consciousnesses to arise together.'
