|Tsa-tsas are a form of Buddhist art that has flourished for centuries in Tibetan areas, in the Himalayas, across the Tibetan plateau and beyond as far as Mongolia. Tsa-tsas are made of stamped clay and are iconographic forms of various Buddhas, Bodhisattvas or sacred mantras. Tsa-tsas can be of various sizes; small enough to fit into a small gao, or charm box, to be worn for protection, or larger, to be left in a sacred area in the memory of a loved one. Stamping tsa-tsas from clay is considered an act to accumulate merit. Tsa-tsas made into conical shape often contain human remains, collected after a funeral, and are also left in holy spots.
