俱舍論疏 19.58

19.58

論「於彼睡時至立隨眠想」，經部答也。有二釋：一是睡時、二因立果名。想即名之別稱，謂於現在位纏立隨眠稱。

On the passage where the Śāstra says, 'At the time when one is asleep [...] the notion of anusaya is established': This is the Sautrāntika's reply. There are two explanations: first, that it is the time of sleep; second, that the name of the effect is established on the basis of the cause. 'Notion' (saṃjñā) is an alternate designation for a name, meaning that with respect to the entanglement in the present state, the designation anusaya is established.
