Tsa Tsas are small sacred images that are hand crafted from clay. The clay is often consecrated with medicinal ingredients and relics and then filled with mantra rolls or stamped on the reverse with mantras. It is a common Dharma practice to make Tsa Tsa to accumulate merit and purify obstacles. They are often placed inside a gau or they may be kept on an altar as a practice support. Like small statues they can depict Buddhas, deities or revered Lamas.
