On Yuan Chwang's Travels in India, 629–645 A.D. v1.c9.s3.8

v1.c9.s3.8

In another Chinese Buddhist work we learn that the Buddha once went to "North India" to the Yue-shi (Getae) country and thence to the west of this. Here he overcame a fierce wicked Rakshasi, spent a night in her cave, and left his shadow on a rock in it like that in the Gopāla cave.² In another Buddhist treatise, moreover, there is mention of a district called Na-kie-lo or Na-kie-han (or a)-lo. Here also was a rākshasi cave, and Buddha came from India to convert the rakshasi and left his luminous image in the cave.³ This cave was in the side of the mountain Ansu, in the Champak grove of the old rishi, close to a Dragon's lake, and north of the Blue-Lotus fountain. The district in which this cave was situated was evidently not the Nagar country of our pilgrim. He also mentions two other caves with luminous images of Buddha in other parts of India.
