In the first, the phrase "therefore" means that because the aforementioned One Mind follows avidyā and stirs to produce the five kinds of consciousness, it is therefore said that the three realms evolve only from the mind. This mind, following perfuming, manifests semblances, which is called "false"; concealing its false substance, it deceptively manifests actual appearances, which is called "deceptive". Although the false and deceptive appearances are of various kinds, when their causes and conditions are investigated, they are made only by the mind. The Daśabhūmikasūtra also states the same. Apart from that manifesting consciousness, there are no dust-objects; inversely verifying that the six dusts are only the One Mind, it therefore says "apart from the mind, there are no...", and so forth.
