大唐西域記 3.10

3.10

摩訶伐那伽藍西北，下山三四十里，至摩愉（摩言豆）伽藍。有窣堵波，高百餘尺。其側大方石上，有如來足蹈之迹，是佛昔蹈此石，放拘胝光明，照摩訶伐那伽藍，為諸人、天說本生事。其窣堵波基下有石，色帶黃白，常有津膩。是如來在昔修菩薩行，為聞正法，於此析骨書寫經典。

Going south about 200 li from the town of Mungali, by the side of a great mountain, we come to the Mahâvana sanghârâma. It was here Tathâgata in old days practised the life of a Bodhisattva under the name of Sarvadata-râja. Fleeing from his enemy, he resigned his country and arrived secretly in this place. Meeting with a poor Brâhman who asked alms from him, and having nothing to give in consequence of his losing his country, he ordered him to bind him as a prisoner and take him to the king, his enemy, in order that he might receive a reward, which would be in the place of charity to him. Going north-west from the Mahâvana sanghârâma down the mountain 30 or 40 li, we arrive at the Mo-su sanghârâma. Here there is a stûpa about 100 feet or so in height. By the side of it is a great square stone on which is the impress of Buddha's foot. This is the spot where Buddha in old time planted his foot, (which) scattered a kôti of rays of light which lit up the Mahâvana sanghârâma, and then for the sake of Dêvas and men he recited the history of his former births (Jâtakas). Underneath this stûpa (or at the foot of it) is a stone of a yellow-white colour, which is always damp with an unctuous (fatty) moisture; this is where Buddha, when he was in old time practising the life of a Bodhisattva, having heard the words of the true law, breaking a bone of his own body, wrote (with the marrow) the substance of a book containing the words he had heard.
