俱舍論疏 16.53

16.53

論「後方死等至唯無表故」，明後死唯無表，以加行是方便故。

The Śāstra [states], from "[if] the other dies later, and so forth" up to "because there is only non-manifest [action]": this clarifies that when death occurs later, there is non-manifest [action] alone, because the prayoga was the preparatory expedient.
