On Yuan Chwang's Travels in India, 629–645 A.D. v1.c7.s9.5

v1.c7.s9.5

South-west from the New Monastery was a *ching-lü* (精廬) or Buddhist temple. This had been built long ago, and had been the resort of Brethren of high spiritual attainments from all quarters. It had been found impossible to keep a record of those who here realized the Four Fruits (that is, became arhats). So topes were erected for those arhats who when about to die made a public exhibition of their miraculous powers; the bases of these topes were very close together and were some hundreds odd in number. But no memorial erection was made in the case of those Brethren, about 1000 in number, who although arhats had died without exhibiting miracles. In this establishment were above 100 Brethren, who were "day and night assiduous at their duties," and one could not tell which was common monk and which was arhat.
