16.19

「離欲界染至純白業盡」者，釋第二頌。欲不善色緣縛斷故，理同欲善，然於此時更斷欲界餘不善業。據與餘業同盡處說，是故總名第九不善。餘文可知。

Regarding "Freeing oneself from the defilements of the desire realm... bringing purely white karma to an end": This explains the second verse. Because unwholesome bodily and vocal form of the desire realm is severed through the severing of the bondage of the object, its principle is the same as that of desire-realm wholesomeness; however, at this time it additionally severs the remaining unwholesome karma of the desire realm. Based on the point where it ends together with the remaining karma, it is collectively called the ninth unwholesome. The rest of the text is clear.
