大唐西域記 5.47

5.47

護法伏外道側，有窣堵波，無憂王所建也，基雖傾陷，尚高二百餘尺。是如來昔於此處六月說法。傍有經行之迹及髮、爪窣堵波。自此北行百七八十里，至鞞索（山格反）迦國（中印度境）。

The opponent, with some emotion, said, "Sir, be not high-minded! If you can expose my words you will be the conqueror, but first take my text fairly and explain its meaning." Then Dharmapala, with modulated voice, followed the principles of his text (thesis), the words and the argument, without a mistake or change of expression. When the heretic had heard the whole, he was about to cut out his tongue; but Dharmapala said, "It is not by cutting out your tongue you show repentance. Change your principles—that is repentance!" Immediately he explained the law for his sake; his heart was opened and his mind embraced the truth. The king gave up his heresy and profoundly respected the law of Buddha. By the side of this place is a stupa built by Asoka; the walls are broken down, but it is yet 200 feet or so in height. Here Buddha in old days declared the law for six months; by the side of it are traces where he walked. There is also a hair and nail stupa. Going north from this 170 or 180 li, we come to the kingdom of Pi-so-kia (Visakha).
