‘Medium’ means acting as a channel for contacting and communicating with the spirits which may include the spirits of the dead and also other divine spirits, guiding spirits, angels, archangels and even cosmic powers. Clairvoyance means seeing things clearly beyond the normal senses. A clairvoyant sees the energy, images and visions not only within himself with his mind’s eye but also outside his body—beyond the veils of matter, space, and time.
