It was a powerful message and an amazing ceremony. They chanted, and systematically dismantled the sand art. Half of the sand was put into little baggies and dispersed to the crowd with the blessing of compassion, and the other half was released into the Yampa River through another ceremony.
If you would like to know more, the library had a blog for the event.
And here are several articles: One, Two.
I'll also post a video I took of the river ceremony.
I went alone, and had a lovely reflective time, but I wished terribly that so many people could have been there. I sat out at the river and looked around and was shocked by how few people I knew or recognized. Where were all of my friends and acquaintances and why weren't they taking advantage of this amazing opportunity? Just as I started to feel a little down about it, I spied a couple familiar faces on the far side of the river. And so, everything was just as it should be.
