From our friends over at Cedar Lane UU:

Tibetan Buddhist monks from Drepung Loseling Monastery will construct a Mandala Sand Painting from August 23 to 27, 2017 at Cedar Lane Unitarian Universalist Church in Bethesda, MD. Millions of grains of sand are painstakingly laid into place in this ancient spiritual art form in order to purify and heal the environment and its inhabitants. The monks will also participate in Sunday worship at 10 a.m. on August 27. At 2 p.m. that Sunday, we will also have our closing ceremony and processional to Rock Creek, to immerse the sand from the mandala. All are invited.
