On Yuan Chwang's Travels in India, 629–645 A.D. v2.c23.s17.3

v2.c23.s17.3

Above 300 *li* to the south-east of the capital was a cliff in which were two caves, each containing an arhat in a trance which had been prolonged for more than 700 years: the bodies were like skeletons, and the only sign of life was that the hair kept growing, and had to be cut periodically. Going to the north-east of this cliff over a mountain for 200 *li* the pilgrim came to a Puṇyaśāla. This had been built and endowed, according to tradition, by an arhat in pity for distressed caravans crossing the wild bleak region.
