The Didgeridoo, an ancient instrument played by the Australian aborigines is now used by many contemporary healers world wide. It has a very soothing low sound that can affect you on a very deep level, be it subconscious or super conscious. While moving over and/or around the body, the sound vibrations often induce healing of the chakra imbalances. The sound is without rests. In order to play this instrument one needs to learn to do the in-breathing while blowing the instrument. Quite an art. You can practice this with a straw in a glass of water.
Nowadays the price of a didgeridoo is not high when you buy it in a store where all kinds of items from many cultures are sold.
Enjoy this wonderful practice while listening to you inner voice.
