成唯識論述記 1.29

1.29

又有二種：一者世俗，即依他起；二者勝義，即圓成實。於前，所斷清淨；於後，所得清淨。

Furthermore, there are two kinds: first, conventional, which is the other-dependent [nature] (paratantra); second, ultimate, which is the perfected [nature] (pariniṣpanna). With regard to the former, it is purity through abandonment; with regard to the latter, it is purity through attainment.
