This is a crystal singing bowl. Isn't it beautiful? I have never actually seen one of these, except on television. I remember an early episode of ER has Dr. Lewis sitting in the bathroom, using one of these to release the tensions of the day. Each bowl has a beautiful sound. The smaller the bowl, the higher and clearer the sound. Larger bowls have a lower, more soothing sound. I love the look of this crystal one. I am sure it would make an interesting conversation piece in any home.These Gongs and bowls are used for meditation, which is something I have been wanting to look into. I need to find a way to relax my mind and body. I have been thinking of looking into yoga, and I think these bowls would compliment that wonderfully.
