I've twice had the good fortune to attend a Tibetan Buddhist Healing Mandala Ceremony. Several monks meditatively work hours to create a Mandala using colored sand and funneling it on to a transportable flat surface with a drawn design. When this beautiful work is completed it is carried to a stream/river and tilted with the sand falling into the running water. With prayer and compassion they enact reality and the impermanent nature of existence.

To me this understanding of impermanence speaks directly to the sustainable movement in the arts, business, education, agriculture, politics, philosophy/religion and etc.
