The crystals in every bowl are able to amplify, store, focus, transfer & transmute energy which can create profound effects on your organs, tissues all the way down to your cells because our bodies are crystalline in structure. They're music therapy. Best to bring a yoga mat, blanket & pillow if desired and water. You will be guided in a short meditation with an option to sit or lay on your mat for the entire session. What students are saying about the Instructor: "The last sound bowl session was truly amazing. I was so deeply relaxed and it was completely an out of body experience! It was so great to release some of that must needed energy and just feel at one again with my body. It's my favorite way to end our wonderful session we have together."
