俱舍論疏 1.252

1.252

論「不爾此已至後識不生」，答也。猶如種子已住因性，闕餘緣故後果不生。後心亦爾，已住意性，餘緣闕故後識不生，而成意界。

Regarding the commentary statement from "It is not so; this has already" up to "a subsequent consciousness does not arise": this is the reply. Just as a seed has already become established in the nature of a cause, but because other conditions are lacking, a subsequent fruit does not arise; the final mind is also like this: it has already become established in the nature of mind, but because other conditions are lacking, a subsequent consciousness does not arise; nevertheless it constitutes the mind dhātu.
