A person with clairvoyant ("clear seeing") abilities can perceive things beyond the range of the five senses. There are many types of clairvoyance, each corresponding to different objects of extra sensory perception. These include objects at a distance or concealed from sight, energies of the psyche, and the world of  spirit. Clairvoyants who are able to see spirits are sometimes able to communicate with them as well.

The third eye, often considered to be the seat of psychic and paranormal powers, is a highly developed clairvoyant channel. Thought to be associated with the pineal gland in the brain, it is located in the centre of the forehead just above the eyebrows. The awakening of the third eye often involves extreme discomfort or even pain. Although it may open spontaneously for a period of time, it usually takes many years of meditative exercises for this to occur.

The third eye can be used in many different ways. It can help transport thoughts or energy from one place to another, enabling someone to communicate at a distance. It can amplify and direct energy from one point to another in order to facilitate healing. In certain psychic disciplines, it can be used to make changes to the body such as spinal adjustments, even at a considerable distance. The third eye can also be used for diagnostic imagery, a process which allows us to view the skeleton, the nervous system, the soft tissue, the auric flow and the energies of the physical body (including internalized mind energy) in order to determine the cause of a problem.

The third eye is a very powerful tool and as such, it has the potential to be misused. With an open third eye, one is able to influence the psyche of another person and not necessarily for the better. Psychic abilities are not reserved for those who intend to use them responsibly. When activating the third eye, it is essential that the clairvoyant maintains a non-emotional, psychologically neutral state of mind so that no harm befalls the one who she is trying to help.
