There are many booths @ this venue, and a portion of the proceeds go to support various people & causes. I noticed this colorful booth.
I came upon this Buddhist Monk, making a sand mandala.
I've seen this art done by Monks a few times, tedious art form carefully tapping grains of colored sand to create an intricate & meditative Mandala.
Usually, they use a metal "straw" with a narrow pen pointed end to tap the grains of sand precisely into the pattern, but this Monk was doing the design all by hand alone. A much more difficult task.
After working for many hours & days on the Mandala, it is then scooped up, and often taken to a river & poured in, to affirm the impermanence of everything.
It was interesting to observe festival goers stop in their tracks to stop & watch this ancient art form take place right before their eyes. Enlightening!
Did I mention they do Dragon Boat races there too?
