This fine clay votive plaque of tsa-tsa is from Tibet and shows the Mahakala, a protective deity in Tibetan Buddhism.
Such tablets were acquired by Buddhist devotees and pilgrims as acts of merit, often at religious sites, as mementos and talismanic or protective keepsakes. The plaques often were made in one location and carried by pilgrims to be left at a site in another location, perhaps in a cave or at an important shrine. According to Proser (2010, p. 167), the practice of spreading tsa-tsa offerings throughout the landscape can be likened to sowing seeds of potential spiritual merit, somewhat akin to laying out ‘fields of Buddhas’ throughout the world.
