13.34

In the specific explanation, first clarifying the perfuming of defilement is in accord with principle. For only after defiled dharmas are first established can one reverse defilement to become pure; there has never been being pure first and subsequently becoming defiled dharmas. If purity were explained first and defilement explained afterward, there would be the fault of delusion arising endlessly, as well as the error of becoming deluded again after enlightenment; therefore, defilement is explained first.
