I have been trying to locate information regarding *Upaśūnya 月婆首那 , active during the 6th century.
There are two entries about him in Bagchi's 1927 Le Canon Bouddhique en Chine (pp. 265-7, 431), but I have not located anything more up to date. Surely, there must be some more recent scholarship. I would be grateful to know of it. Bagchi (p. 431) attributes a version of the Vimalakīrtinirdeśa to him, but this seems to be a confusion and Lamotte, in his discussion of the Chinese translations, does not mention it. However, I am primarily interested in the other translations credited to 月婆首那 .
thank you in advance,
