As for the perfuming of the manas: in terms of the fundamental, it is called the karmic consciousness; speaking generally, it refers to the aforementioned five kinds of manas. Because bodhisattvas know that all dharmas are nothing but consciousness, they abandon the external discrimination and conceptualization of that empirical consciousness; having realized mind-only, they advance toward the principle swiftly, differing from the prior gradual awakening. Therefore it says, down to "swiftly advance toward nirvāṇa."
