Answer: Because the five consciousnesses equally lack the activities of discrimination, taking objects, and so forth to be explained, and the matters explained are few, they are combined into one and spoken of first; the mental stage is the reverse of this, hence it is separately established as one and spoken of second. Furthermore, because the five consciousnesses equally rely on material faculties and equally take material objects as their domain, they are combined into one. The other [consciousness] relies on the non-material and its objects are not fixed, hence it is separately established as one. In terms of their intrinsic nature, supports, and objects, there is a sequence from coarse to subtle, hence they are spoken of in this order. Furthermore, because the five consciousnesses are equally subsumed under direct perception (pratyakṣa), they are combined into one and spoken of first; the other consciousness is not fixed, being subsumed under direct perception, inference (anumāna), or non-valid cognition (apramāṇa), hence it is separately established as one and spoken of second.
