俱舍論記 6.234

6.234

「共業生故」者，答。由共業生，故得共受。又《正理》十八云「豈不大梵所住非情是別業果，亦應說彼名業異熟。何乃言非？有作是言：大梵住處，一切大梵業增上生。有餘復言：大梵住處相續未壞，餘可於中有受用理，故非不共。

Regarding 'Because it is produced by common karma': An answer. Because it is produced by common karma, it can be experienced in common. Furthermore, the Nyāyānusāra, fascicle 18, states: 'Is not the non-sentient realm inhabited by Mahābrahmā the fruit of distinct karma, and should it not also be said to be the ripening of karma? Why then say it is not? Some say: The dwelling place of Mahābrahmā is produced by the comprehensive dominance of the karma of all Mahābrahmās. Others again say: So long as the continuum of Mahābrahmā's dwelling place has not disintegrated, it is reasonable that others may have experience therein; therefore, it is not unshared.'
