The rainbow-colored energy centers of man are understood and expressed in Judaism as the seven heavens, Christianity as the seven sacraments, the Kaballah as the seven tiers, and in Buddhism and Hinduism as the seven chakras. These centers serve as the place of the exchange of energy from the spiritual world to our world and the colors expressed in this picture depict each in its most purified form.
“The final mystery is oneself. When one has weighed the sun in the balance, and measured the steps of the moon, and mapped out the seven heavens star by star; there still remains oneself. Who can calculate the orbit of his own soul?” — Oscar Wilde
