Mold for votive tablets with the Buddhist deity Hevajra

Only two dancing yoginis flank Hevajra on this small mold, but presumably they stand for the usual eight. Several metal molds for making terra-cotta tablets of Hevajra are known, but this is the only extant one of earthenware. The existence of molds suggests that tablets were needed in some numbers, but nothing is known about how they were used. Did they have a function in rituals? Were they offerings? Did the more elaborate ones have a different purpose from the simpler ones that would have been made from this mold? Future archeological research may help resolve these questions.
