4.61

復次，染熏習從無始來不斷，成佛乃斷。淨熏習盡於未來畢竟無斷，以真如法熏習故，妄心則滅，法身顯現，用熏習起故無有斷。

"Furthermore, defiled perfuming has been uninterrupted from beginningless time, and is interrupted only upon attaining Buddhahood. Pure perfuming continues to the end of the future and is ultimately never interrupted, because through the perfuming of the dharma of tathatā, the deluded mind is extinguished, the dharmakāya manifests, and the perfuming of function arises, so there is no interruption."
