After jostling your way through the mad rush of devotees entering the Shrinathji Temple in Nathdwara–a pilgrim town in Rajasthan–tarry a while as you have a ‘darshan’ of the deity. Look beyond the idol, at the painting which serves as a backdrop. Because this is what has added a special chapter to Indian art. Known as Pichhwai, these backdrops are part of the Nathdwara school of miniature art, a subsect of the Mewar school of painting.
