大唐西域記 7.8

7.8

精舍西南有石窣堵波，無憂王建也，基雖傾陷，尚餘百尺。前建石柱，高七十餘尺。石含玉潤，鑒照映徹，慇懃祈請，影見眾像，善惡之相，時有見者。是如來成正覺已初轉法輪處也。

To the south-west of the vihara is a stone stupa built by Asoka-raja. Although the foundations have given way, there are still 100 feet or more of the wall remaining. In front of the building is a stone pillar about 70 feet high. The stone is altogether as bright as jade. It is glistening, and sparkles like light; and all those who pray fervently before it see from time to time, according to their petitions, figures with good or bad signs. It was here that Tathagata (Ju-lai), having arrived at enlightenment, began to turn the wheel of the law (to preach). By the side of this building and not far from it is a stupa. This is the spot where Ajnata Kaundinya ('O-jo-kio-ch'in-ju) and the rest, seeing Bodhisattva giving up his austerities, no longer kept his company, but coming to this place, gave themselves up to meditation. By the side of this is a stupa where five hundred Pratyeka Buddhas entered at the same time into Nirvana. There are, moreover, three stupas where there are traces of the sitting and walking of the three former Buddhas.
