From all the artistic traditions of Tantric Buddhism, that of painting with colored sand ranks as one of the most unique and exquisite. In Tibetan this art is called dul-tson-kyil-khor, which literally means "mandala of colored powders." Millions of grains of sand are painstakingly laid into place on a flat platform over a period of days or weeks. Formed of a traditional prescribed iconography that includes geometric shapes and a multitude of ancient spiritual symbols, the sand-painted mandala is used as a tool for re-consecrating the earth and its inhabitants.
