Tibetan Monks
Here are the pictures of the mandala and the ceremony of it's dismantling.

1. The sand and instruments used to create the mandala
2. The mandala itself, in completed form (unfortunately, I don't have a picture of the monks working on it, though we did see them)
3. Close up detail #1... notice the layers and coloring, all loose sand
4. A close up of the center of the mandala. Each colored section represents some aspect of harmony or balance.
5. The monks chant and play some jazzy music before dismantling the mandala
6. A weird blurry close up of the gnarliest old monk... out of focus but I like it
7. Sweeping the sands of the mandala. The old guy first consecrated the center of the mandala and then blurred it inwards from the six spokes you can see here.
8. All that colorful sand, now greyish brown... putting the sand into bags for the audience
9. The procession to the river begins.
10. Ojiisan again...
11. The procession at the river in full garb
12. Ojiisan pours sand, offerings, and some liquid (from this kettle) into the Willamette.
