As for "can contain all dharmas": in the above two gates it said that each comprehensively contains [all dharmas]. Here it does not say "each", because these two meanings are narrower than the two gates; it only explains the one consciousness. Because it contains the two meanings, it contains all [dharmas]; it does not say that each of the two meanings contains all [dharmas]. Furthermore, in the text above it only said "contains" and did not say "produces", because the gate of tathatā has no meaning of being able to produce. In this consciousness, because non-enlightenment perfumes innate enlightenment, it produces all defiled dharmas, wandering in saṃsāra; because innate enlightenment perfumes non-enlightenment, it produces all pure dharmas, reversing the flow to emerge from entanglement and accomplishing incipient enlightenment. Relying on these two meanings, it produces all defiled and pure dharmas everywhere; therefore it says "it can produce". This will be discerned in detail below in [the section on] the four perfumings. Not only does mutual perfuming produce all dharmas, but after producing all dharmas they do not depart from this mind, being contained by this mind, just as explained above where the two gates each contain [all dharmas].
