Just as the various forms of yoga attempt to mediate between the physical and spiritual realms, so the chakras are believed to operate as energy transformers. They are often shown as circles, spaced at intervals along the spine, or sometimes as funnels of energy. Specific chants or sounds associated with the different chakras are used in some yogic meditation practices as tools for healing and spiritual evolution.
Each of the seven chakras is said to have specific physiological and metaphysical functions that relate to both the nature of the associated blockages and to the physical problems they produce.
Base/root chakra (muladhara). The first chakra, located at the base of the spine, is linked with basic survival and with the adrenal glands. It is associated with the color red and the earth element.
Second chakra (svadisthana). Thought to reside in the genital region, this chakra is linked with sexuality and with the reproductive system. It is associated with the color orange and the water element.
Third chakra (manipura). Situated near the navel, this chakra is linked with the pancreas and the solar plexus. It is associated with the color yellow, the fire element, and power in the world.
Heart chakra (cnahata). The fourth chakra, associated with the heart and the immune system, is believed to be the seat of love and compassion. It is associated with the color green and the air element.
Throat chakra (visuddha). The fifth chakra, situated in the throat area, is associated with the thyroid gland, the color blue, and communication.
Brow/forehead chakra (ajna). The sixth chakra, also known as the “Third Eye,” is said to reside in the forehead. It is associated with hormonal production, the color indigo, and intuition.
Crown chakra (saha srara). The seventh chakra, located at the top of the skull, is associated with elevated spiritual consciousness, the pineal gland, and the color violet.
