The book explains how the codes are related to the chakras and how each chakra holds an emotional aspect that may not be in harmony with our mind-brain response to a particular issue. Listening to a code is one way to help us re-balance ourselves from an emotional upset and align with our heart's intuition.
The Quantum Healing Codes™ CD includes the six fundamental solfeggio codes plus 16 additional combinations, including the Open Heart Chord.
