The aura therefore may be called a visible atmosphere, or the atmosphere an invisible aura. Just as different degrees of the vibrations of the atmosphere have a distinct influence upon the person who perceives them, so the different colors of the aura have their particular effect upon those who see this aura. There are many who are not yet awakened to perceive an atmosphere, to see an aura, although they will feel it in the depths of their being; they cannot help it.
