Tsa Tsas are small hand made sacred images crafted from clay using a metal mould. They represent the enlightened form of Buddhas, Yidam deities and revered lineage Lamas. Each piece will typically be made from clay, blessed medicinal ingredients and filled or stamped with mantras and relics. It is a common practice to make Tsa Tsa to accumulate merit to purify obstacles to longevity. The making of Tsa Tsa might also be incorporated into other Vajrayana practices. Some Tsa Tsa contain the ashes of revered Lamas and these are believed to carry potent blessings. They can be placed inside a reliquary or gau and then worn on the body as an amulet, or they may be kept on a shrine and treated in the same way you would a consecrated statue.
