The Chakra Set is a set of Tuning Forks that can be used with the chakra system. There are 7 Tuning Forks in this set. It is based on the mathematical rotation of the planets around our Sun. These forks are NOT based on a musical scale. They work more on the cosmic multi-dimensions of our chakras, our not noticeable bodies or subtle parts. They also work on pathways as well as other gateways of energy. The planetary cycle of the solar System is used to arrive at accurate formulae on which these tuning forks have been created. This links them to our cosmic multi-dimensional selves. Our this self is eternal, very not noticeable and approachable through layers, ladders, gateways and manifold levels of energy. These Tuning forks prepare pathways to a Cosmic Universal understanding of Life and our Soul's infinite relationship to it.
