A sand mandala is made up of millions of grains of sand, laid in place using hollow pipes called chak-purs, through which the sand is vibrated into the design. It’s a vehicle to generate compassion, and highlight the impermanence of life and reality. Tightly balanced and geometric, the mandala houses deities, including the principal deity who dwells in the center.  Monks meditate upon the mandala, imagining it as a three-dimensional palace. [wpvideo EuNYcFFt]
