Since time immemorial throughout the world, all peoples have known of the power of sound and music for healing the mind, body, Soul, & emotions.
All people can trace their Ancestry back to a time when these ways were common, and many Indigenous people still practice these healing modalities today.
The voice and drums are often used in order to go into trance in order to “journey to the otherworld”, in order to access healing through various means. Throughout the world, one can find commonality amongst diverse peoples in that, they all speak of an Upper, Middle, & Lower world. These can be described as collective inner planes of consciousness that actually exist.
