Crystal singing bowls are a fabulous way to get the brain waves from high beta (stress) into theta (deep relaxation). When deciding which bowl to purchase it is important to consider the size, thickness and type of gemstone infused as each one varies in sound and healing properties. Bigger bowls have a deeper frequency and smaller bowls will have higher frequencies. Crystal singing bowls are excellent for balancing chakras as each note corresponds to a chakra. Chakras are able to give us information about our emotional, mental and even physical health. Getting familiar with these energy centers will make it easier when choosing a sound bowl. Yet you will never go wrong with whatever you decide as each one contributes to our overall health.
