From all the artistic traditions of Tantric Buddhism, that of painting with coloured 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.

Traditionally most sand mandalas are destroyed shortly after their completion. This is done as a metaphor of the impermanence of life. The sands are swept up and placed in an urn; to fulfill the function of healing, half is distributed to the audience at the closing ceremony, while the remainder is carried to a nearby body of water, where it is deposited. The waters then carry the healing blessing to the ocean, and from there it spreads throughout the world for planetary healing.
