Agates are multi-colored and will work on many levels for healing. They engage primarily with both the physical and emotional levels of the energy field.
Because of the complex play of frequencies in agates, they will move outward from the physical layer of the energy field and into the other layers of the field, integrating them and grounding in the healing that is necessary in a particular body.
Banded agates strengthen spiritual vision. They aid in determining the etheric cause of physical symptoms and in healing on all levels.
