俱舍論記 5.27

5.27

「居在廣果至名無想天」者，答。明所居處。廣果天中有高勝處，無想有情而居其上。如中間定梵王，於梵輔天中起臺別住。此亦如彼，名無想天。

"They dwell in [the Heaven of] Vast Fruit (Bṛhatphala)... called the Heaven of Non-Conceptual Beings (Asaṃjñisattva)," answers the text. This clarifies their dwelling place. In the Heaven of Vast Fruit, there is a sublime, elevated place where non-conceptual sentient beings dwell. Just as in the intermediate dhyāna, the Great Brahmā dwells separately on an elevated terrace among the Brahma-purohita heavens; this is also like that, and is named the Heaven of Non-Conceptual Beings.
