Clairvoyance means clear seeing. A clairvoyant is a person capable of deep concentration of thought. Through concentrating, he tunes his mental organization in harmony with that of other people, and thus receives thoughts and messages from them. Clairvoyance was supposed to be a distinct power or gift. This is not so, for each and every person possesses the same ability though in a greater or less degree of development. Clairvoyance is Mentalism, in operation. A clairvoyant is the servant of others, and often becomes a slave to the influence of the combined Mentalism of the public. When this is the case he soon loses all his individuality and Will Power. The moment one acts in the capacity of a receiver of messages for others, he resigns his own Will to theirs, and thus loses his individuality. Every person should be his own clairvoyant, but he should not sell himself and sacrifice his Will and independence to others for the paltry financial remuneration he would receive in return for it.

A Medium is another name for a Clairvoyant, but it is most generally applied to a Spiritualist who acts as a dispatcher and receiver of messages, for those who do not understand the law that governs the phenomena. The person acting in that capacity should rightly be called a Mentalist, and not a Medium or Clairvoyant.
