The key to our self-transformation lies in the vibrational spin of the chakras. The closer their frequencies are to the optimum the more we become who we really are and produce sound health at every level. Through the process of therapeutic vocal sound the chakras are stimulated and balanced, releasing fine energies. Four pathways are followed: toning, the sounding of mantras, ritualising natural sounds and chanting complemented by simple movements that encourage and direct the sound. Inner sound is explored leading to the meditation state where the greater healing lies. James D’Angelo, based in England and author of the The Healing Power of the Human Voice, has been leading therapeutic sound courses and workshops in the UK, Europe and the USA since 1994 and is considered an authority on sound healing practices.
