俱舍論疏 20.136

20.136

論「見滅見道至十一識緣」，已下明三界見滅、道所斷也。若欲界者六識，乃至十者十一識緣，皆增自識。不增二者，滅、道所斷，不互緣故。

The Śāstra says: "Abandoned by seeing cessation and seeing the path […] are objects of eleven consciousnesses." Below, it explains those abandoned by seeing cessation and the path across the three realms. If of the desire realm, six consciousnesses, up to ten being objects of eleven consciousnesses; each adds its own consciousness. The reason two are not added is that those abandoned by seeing cessation and the path do not mutually take each other as objects.
