Unblock the Bridge to Your Mystical Self
There are multiple layers to the human energy field. Aspects of the light body include the etheric body, mental body, astral body, and emotional body.
The Astral Layer is the fourth energetic light layer in the aura which is of the heart. Here lie issues of love, connection, affinity and oneness. This is both a link between the body, mind, and spirit and a connection with all other people and living creatures on Earth. This layer can reach a length of one foot. It serves as a link between the physical plane's lower vibrations and the spiritual plane's higher vibrations. This layer, which is linked to the heart chakra, is symbolized by a lovely rainbow color.
