This Floor Painting style is a part of Tibetan Tantric Art tradition. The Tibetans call it 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. The heartbreaking part of this ritual is that after days of determined hard work and perseverance the very monks who work on these paintings have to destroy them.
The beginning of mandala sand painting is an auspicious occasion which is marked by a ceremonial ritual. In this opening ceremony the lamas, or Tibetan priests, gather in front of the painting the site and call forth the supreme power of goodness. This is done by the means of chanting, music, and mantra recitation.
In the first day of the painting process the outline of the painting is drawn on a wooden board. In the consequent days the outlines are layersed with different colored sands. The sand is poured from a metal funnel called chak-pur. This funnel is an important part of the tradition too. The monks involved in the apintings hold a funnel in their hand and run a metal rod on its surface. The vibrations caused by the metal rod makes the sand flow like water from the funnel mouth.
These paintings follow the prescribed Mandala motifs. A Mandala is a symbolic geometric pattern, which is a metaphysical or symbolical representation of the cosmos, a microcosm of the universe from the human perspective. The center of the Mandala can be used as the focal point of meditation. In fact the complex but symmetric web of structures around the center draws one’s eyes towards the focal point.
