"Of all the traditional Tibetan tantric practices, the art of painting  with colored sand is one of the most unique and exquisite. In Tibetan  language, 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 before ultimately being  dismantled in order to release and disseminate the deity's blessings  into the world to benefit all sentient beings.
 Formed into traditionally prescribed Tibetan iconography that  includes geometric shapes and a multitude of historical Buddhist  spiritual symbols, the sand-painted mandala is used as a tool for  consecrating, or blessing, the earth and its inhabitants, and provides  for the practitioner a visual framework for establishing the enlightened  mind of the Buddha."
