Colored Sand Mandala
A Mandala (from Sanskrit Mandala means “circle”) is a ritual symbol in some Indian religions and some forms of Buddhism. The base shape is a square with four “T”-shaped gates, containing a circle. Traditionally it represents the cosmos or a part of the universe. Can be used for improving focusing during meditation or as a spiritual guidance tool.
The Tibetan monks you see are creating a Mandala from colored sand. This exercise helps them develop difficult to master traits like patience and calmness. The work is extremely precise – the outline is filled using a special tool that paints with a thin flow of sand. The elements are very fine and every mistake is almost impossible to be corrected. Notice that the “painting” is not flat, it has layers, which makes it more beautiful but also more difficult.
