Tibetan monks and their sand mandalas
These particular monks came to visit The American Visionary Art Museum this past summer and during their week long visit they created this beautiful sand painted mandala. Upon its completion, they blew the entire artwork into the harbor.
Commonly: A generic term used to describe any plan, chart, or geometric pattern that represents cosmos metaphysically or symbolically on a micro or macroscopic scale.
Many mandalas contain the lotus flower in the center.
