Dear Dan, 

I find this website very useful when looking up toponyms: http://india.csis.u-tokyo.ac.jp. That said, I didn't find anything conclusive. 

My hunch (very scholarly, I know...) is that it could be Sylhet through a progressive corruption of Śrīhaṭṭa (e.g. *Sirihaṭ ṭa, *Sarahaṭṭa, etc.) and finally Tibetan editors trying to make some sense out of the reading. 

Best wishes,
Peter

Dear helpful colleagues,

In Volker Caumanns’ book, Shakya-mchog-ldan, Mahāpaṇḍita des Klosters gSer-mdog-can (Wiesbaden, 2015), he presents material on an Indian monk in Tibet named Lokottara, who self-identifies as of the Sāṃmitīya nikāya, and says his home is in eastern India, in a place called Saṃgharatna. This is 15th century. I know of a Saṃgharatna in Kerala, but not one in eastern India. Would anyone have a clue where that might have been (still is?), and what might correspond to it in today’s India?

Thank you.
Dan
