Crystal healing is a holistic, non-invasive, vibrational energy-based system of healing. This modality uses precisely placed crystals on and/or around the physical body. Crystals absorb, focus, direct, detoxify, shift and diffuse energy as they interact with the electromagnetic forces and subtle vibrations within the human or environmental energy field. In the context of crystal healing, illness is "dis-ease", the final manifestation of spiritual, environmental, physiological, psychological, emotional, mental, karmic, or ancestral imbalance or distress. The term "Healing" means bringing mind, body, spirit and environment back into harmony, restoring the body’s natural rhythm and equilibrium. The term "Karma or Karmic healing" means to release past life imprints to allow for spiritual growth and alignment to our higher mind. The main influence for crystal healing is the chakra philosophy of disease caused by energy imbalances. Crystal healing can also be performed using crystal grids (crystals laid in precise geometric patterns) within the environment.
