You can see the ends of the long horns here, and the monks pouring the sand into the water. It was an excellent experience and I am waiting for them to come again.
One note about this experience. Some of my favorite stitching pieces are very much like mandalas. It has been inside of me a long time, tho I never knew it till the monks came. I went to BN and got a mandala coloring book for me, and when I am particularly stressed I take it out and create my own. It is a great release, very relaxing to me.
