According to Hindu tradition, the Ajna, brow, or third eye chakra is the body's sixth primary chakra. It is centered in a part of the brain that can be made more powerful through meditation, yoga and other spiritual practices. It signifies the subconscious mind, and is the direct link to the Brahman. While a person's two physical eyes see the physical world, the third eye reveals spiritual insights. This one is indigo, with a centralized diagram of the third eye.
NOTE: The third eye chakra connects one to their intuition, gives them the ability to communicate with the world, and assists them in receiving messages from the past and the future.
