What is Sound Healing?
SUL Crystal Bowls


Sound Healing is the use of sounds and vibrations which can be a combination of various instruments (crystal singing bowls, gongs, Tibetan singing bowls, tuning forks etc) or voice to relax the mind, bring the body back into balance and stimulate the brain into to a more relaxed state.

SUL Crystal Bowls


Sound Healing is the use of high vibrational sounds or frequencies. Research has shown that liquids move in specific patterns in the presence of sound frequencies. Our cells are filled with fluid as the human body is made up of more than 70% water, so sound frequency stimulation effects us deep at a cellular level. The sound vibrations/frequencies relax both our nervous system and brain waves and these enable our body to go into a self-healing mode. In this state, the emotional and energetic blockages may also be released.

Yantara Jiro Sound Healing


Sound Healing dates as far back as Ancient Egypt and its benefits range from deep relaxation to cellular repair. The harmonic sounds and vibrations stimulate the beta, alpha, theta, delta and gamma brain waves, inducing a deep peaceful state or meditation. Some of the benefits include a reduction of stress and anxiety, strengthening of the immune system, improved sleep, a calmer and more peaceful state of being, tension release, clearing blocked energy and rebalancing the chakras.
