燈約等者。以膏油喻貪愛，以燈喻識，若無膏油則燈光不起，若無貪愛則識念不生。故論云：「依止貪愛法住。」然此上三喻，皆是能熏染污根本，故通名自性相。其所熏第八識持種引心，配屬雲喻如下所明。或可星喻見分，翳目所見毛月喻相分，燈喻自證分，自證分即第八識。其後雲喻，但況識中種子為未來法。

"The lamp in terms of, etc.": using oil to symbolize craving and the lamp to symbolize consciousness: if there is no oil, the lamp's light does not arise; if there is no craving, conscious thoughts do not arise. Therefore the treatise says: "Abiding dependent on the dharma of craving." However, these three similes above are all the root of defilement that can perfume; hence they are generally named the mark of own-nature. The perfumed eighth consciousness, which holds seeds and induces the mind, is matched to the cloud simile as explained below. Alternatively, the star symbolizes the perceiving aspect, the hair-moon seen by the cataract eye symbolizes the perceived aspect, and the lamp symbolizes the self-authenticating aspect—the self-authenticating aspect being the eighth consciousness. The later cloud simile merely compares the seeds within consciousness as future dharmas.
