How the Sand Mandala Is Created
The lamas begin the work by drawing an outline of the mandala on the wooden platform, which requires a large part of the day. The next few days are spent laying the colored sands, which is done by pouring the sand from traditional metal funnels called chak-pur. Each monk holds a chak-pur in one hand, while running a metal rod on its grated surface; the vibration causes the sands to flow like liquid.
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.
