A reviewer wrote about the execution of a Kalachakra sand mandala
by Tibetan Buddhist monks at the Museum of Natural History in New York:

Politically, the mandala….offers more than idle prayers for peace;
it is a tapestry of benevolence, harmony, ego-death and antimaterialism itself….
Aren’t these the kinds of ideas that our art should be raising,
and that our culture as a whole should be facing?
