The Commentary states: This means fundamentally existing seeds also depend on perfuming to become robust before they can attain fruit; for newly perfumed ones this is logically obvious, hence it is said that internal seeds definitely have perfuming. The opponent asks again: 'This meaning may be so, but how can it be said that the perfuming of hearing is perfumed into arising by hearing the correct Dharma flowing out from the pure dharmadhātu? And why is it further said to be the seed nature of the supramundane mind?'
