Sariputras disciples village and relic stupa: In his book Huen Tsang mentions Sariputras disciples stupa. This is on a hillock. He doesn't give the disciples name but just the bearing. Near to this stupa is the village of Sarbhadda which sounds very similar to Sariputra. sarbhadda could be Sariputras disciples village. Below is the report I gave to the Archaeological survey of India pertaining to this stupa.

(43)Sariputras disciples stupa/Patharkatti: (Si-Yu-Ki page 180 first para) Four or five Li’s or approximately 4700 ft south east from Kodihara village Huen Tsang visited the stupa of Sariputras favorite disciple. This is on a hillock in a place called Patharkatti. I will quote the second paragraph of page 180 of his book Si-Yu-Ki. He writes, “Four or five li’s south east of the town of Kalapinaka is a stupa. This is the spot where a disciple of Sariputra reached nirvana.” Unknowingly the Bihar Government has built a guest house for pilgrims just below the stupa. The video is available in my youtube channel “Buddha Exhumed.”
