Kalachakra is a Sanskrit word for “Wheel of Time.” This mandala is handpainted by Ratna Kumar Lama from Nepal.
The Tibetan word for mandala is "kilkhor" which means "center of the circle with exteriors walls and the surrounding environment."
Mandalas may be created with precious jewels, flowers, dyed rice, colored stones, or colored sand.
Sand, traditionally made from crushed precious stones, is considered the most efficacious materials because of the precious substances involved and the great skill required to create the mandalas' exquisite details.
Since each grain of sand is charged with the blessings of the ritual process, the entire sand mandala embodies a vast store of spiritual energy.
