Let yourself relax, center yourself and bring your mind back home when you are playing with the Sound Bowl. Hold it on the open palm of your hand and tap it or keep playing around the rim, observing the vibration & sound as it goes along. 
The vibrations & sound of the singing bowls can produce beneficial changes in the body by reducing stress, opening & balancing the chakras, harmonizing the cells, and can even stimulate the immune system and produce beneficial changes in brain waves.
