If you live in, or are passing through London in the next few weeks you might like to visit a free exhibition currently on at the British Museum. It is roughly arranged around the Three Jewels, and although not very large, includes a number of good Buddha rupas and texts from the museums archive, that aren't normally on display.http://www.britishmuseum.org/whats_on/all_current_exhibitions/buddhism_across_asia.aspx
The reason for posting this here in the Jonang section, is that the exhibition includes (somewhat incongruously in a cabinet marked 'arhats') a rather striking metal rupa of Dolpopa Sherab Gyaltsen. Unfortunately there is no catalogue and there is a ban on photography in this part of the museum, so I can't post a picture.
Edwards: You are a philosopher. Dr Johnson: I have tried too in my time to be a philosopher; but, I don't know how, cheerfulness was always breaking in.
