【因陀羅執羅窶訶】《西域記》云：「唐言帝釋窟。西峯南巖間，有大石室，廣而不高，佛常中止。時天帝釋，以四十二疑事，書石請問，佛為演釋，其迹猶在。」

[Indraśailaguhā] The Record of the Western Regions says: 'In the Tang language it is called the Cave of Śakra. Between the southern crags of the western peak, there is a large stone chamber, wide but not high, where the Buddha often stayed. At that time Śakra, king of the gods, wrote forty-two points of doubt on the rock to make inquiries, and the Buddha expounded and resolved them for him; the traces of this still remain.'
