The third eye is an invisible eye, usually depicted as located on the forehead, which provides perception beyond ordinary sight. In Hinduism, the third eye refers to the ajna chakra. In both Hinduism and Buddhism, the third eye is said to be located around the middle of the forehead, slightly above the junction of the eyebrows, representing the enlightenment one achieves through meditation.

Clairvoyance is the claimed ability to acquire information that would be considered impossible to get through scientifically proven sensations, thus classified as extrasensory perception, or "sixth sense". Any person who is claimed to have such ability is said to be a clairvoyant.
