Like most healing tools, mind machines are not a panacea. Nor do they do the work for you. If you don't want them to work, they won't. However, like the trance inducing flicker of fire and the rhythmic pounding of drums in tribal ritual, they draw us nearer to ourselves. The mind machine is a tool, perhaps a tool for modern ritual.
Mind machines play upon the best in our senses.
They draw awareness to an inner place of quietude. A place much forgotten by many in today's society.
