From the cover:

The human body is made up of frequencies that form a harmonic and balanced whole when a person is healthy. However, when a person is exposed to physical and emotional stress, the vibrations of the body may become out of tune. In Vibrational Heling through the Chakras, author Joy Gardner provides the most up-to-date information on the ability of vibrational tools to help the body remember its own harmonic resonance. Exploring the use of color, crystals, oils, aromas, light therapy, and sound healing, this in-depth look at vibrational healing is a scientific, historical, and practical guide for people interested in improving their own health and well-being, as well as those who want to become practitioners of this gentle science.
