The rattle drum was an object used by religious officiants. Nowadays, it is still used by Tibetan Buddhist monks in the form of a wooden hourglass recalling the two cranial skins united by their summit, formerly in common use. In Nepal, Newar Buddhists and street vendors in the Kathmandu Valley still use them.

The one of the Musée Guimet is surmounted by a large, cross-legged male figure surrounded by four smaller female figures holding a lotus flower in their buds.
