Lama Tenzin Yignyen creates a Tibetan sand mandala during the Ecofest at the World Financial Center in New York on Sunday, October 10, 2010. Mandalas, which represent the dwelling of a deity, are created in the spirit of impermanence and are not meant to be inspire attachment. After completion the artwork is dismantled and the sand is given to a body of water, in this case the Hudson River. (© Richard B. Levine)
