3.105

云何熏習起淨法不斷？所謂以有真如法故能熏習無明，以熏習因緣力故，則令妄心厭生死苦、樂求涅槃。以此妄心有厭求因緣故，即熏習真如。

How does perfuming give rise to pure dharmas without interruption? It is because the dharma of tathatā exists that it can perfume avidyā; through the power of the causes and conditions of this perfuming, it causes the deluded mind to feel revulsion toward the suffering of birth-and-death and happily seek nirvāṇa. Because this deluded mind has the causes and conditions of revulsion and seeking, it immediately perfumes tathatā.
