'Arthuna temple, 11th-12th century AD, Rajasthan, India' - by K J S Chatrath

Do notice the small figure at the bottom of the photo. The person so depicted has an unusual hairstyle, is sporting a beard, and seems to be carrying something like a 'gadda' (as of Lord Bhima?) in his hand. It may also be noted that both a Buddhist and a Hindu figure are seen side by side in the same temple. 

Any comments please?
