Mandala is a kind of Dharma instrument provided by Tibetan Buddhism. It is called Mandala in Sanskrit and "jikuo" in Tibetan. Mandala originated from the tantric Dharma practice in ancient India. At that time, in order to resist the invasion of "demons", people built a circular or square Earth altar at the site of Tantra practice, invited the past, present and future Buddhas to testify on the altar, and drew their images on the altar, which constituted the basic framework of the future Mandala. As a symbol of the origin of the structure of the universe, the mandala is a model epitome of the diverse Buddha and the settlement of Buddhas. The significance of offering the mandala of great Weide is to use the most precious treasures in the world to fill three thousand worlds and offer them to the three treasures of Buddha, Dharma and monk. The mandala is exquisitely carved and finely made. It adopts various techniques such as hammer, chisel, tired, stacking and filling, reflecting the superb craftsmanship of craftsmen, which is very rare.size
