大唐西域記 9.52

9.52

迦羅臂挐迦邑東南四五里，有窣堵波，是尊者舍利子門人入涅槃處。或曰：迦葉波佛在世時，有三拘胝（拘胝者，唐言億）大阿羅漢同於此地無餘寂滅。

He then bade adieu to the disciples and came to his native village. His followers, the Srâmaneras, spread the news everywhere through the towns and villages. Ajâtasatru-râja and his people hastened together as the wind, and assembled in clouds to the assembly, whilst Sâriputra repeated at large the teaching of the law. Having heard it, they went away. In the middle of the following night, with fixed (correct) thought, and mind restrained, he entered the Samâdhi called "final extinction." After awhile, having risen out of it, he died. Four or five li to the south-east of the town Kalapinaka is a stūpa. This is the spot where a disciple of Śāriputra reached Nirvāṇa. It is otherwise said, "When Kāśyapa Buddha was in the world, then three kōṭis of great Arhats entered the condition of complete Nirvāṇa in this place." Going 30 li or so to the east of this last-named stūpa, we come to Indraśailaguhā mountain (In-t'o-lo-shi-lo-kia-ho-shan). The precipices and valleys of this mountain are dark and gloomy. Flowering trees grow thickly together like forests. The summit has two peaks, which rise up sharply and by themselves. On the south side of the western peak between the crags is a great stone house, wide but not high. Here Tathāgata in old time was stopping when Śakra, king of Devas, wrote on the stone matters relating to forty-two doubts which he had, and asked Buddha respecting them.
