The human aura is an Energy Field. the Etheric field that surrounds, penetrates and extends out beyond the physical body. It is electromagnetic, electric and magnetic and is made up of varying types of live and intelligent vibrations or frequencies.
Also called a "biofield", the Aura serves two opposing functions. Like a suit of armor, it keeps discordant energies away from your body; like a radio antenna, it channels harmonious energies into your body. As a suit of armor, your Aura filters and screens harmful energies protecting you from undesirable physical, emotional and psychic energies in your environment. As an antenna, it connects you to nourishing energies in your environment.
