The meaning of the perfuming of tathatā is twofold. What are the two? First, the perfuming of its own essence and marks; second, the perfuming of its function. The perfuming of its own essence and marks means that, from beginningless time, it is fully endowed with untainted dharmas and possesses inconceivable activity, acting as the nature of objective realms. Always perfuming based on these two meanings, because it has power, it can cause sentient beings to feel revulsion toward the suffering of birth-and-death, happily seek nirvāṇa, confidently believe that their own bodies have the dharma of tathatā, and give rise to the aspiration to cultivate practice.
