阿素洛（此云非天古譯云不飲酒神也常與三十三天力爭勝負為簡別故故云非天有大神通幻力能現大身自在無礙也）。

阿素洛 (Rendered here as 'non-god' [asura]; anciently translated as 'spirits who do not drink wine'. They constantly vie for supremacy with the Thirty-three Gods. To distinguish them [from the gods], they are called 'non-gods'. They possess great supernatural transformations and can manifest vast bodies, unobstructed and free).
