The word psychic is derivative of the Greek word psychikos meaning "of the mind" or "mental". It usually relates to someone who has the ability to see things through extrasensory perception. Many people are sceptical about the validity of those who claim to possess psychic ability; however there is quite a lot of evidence to show that extrasensory perception does exist. Not to say there are not a whole host of scrupulous individuals out there who seek to take advantage of the believers and fool people into thinking they have certain abilities when they actually don't.
The term ESP or extrasensory perception was coined in 1870 by Sir Richard Burton, this is the earliest finding of the phenomenon actually being given a title. However it is believed that extrasensory perception has existed since the beginning of time. The ability to see outside the realms of the five senses is sometimes referred to as the sixth sense. Psychic readings have been used as a way of giving people insight into a particular situation that they may not have the ability to understand themselves. For example people who feel anxious about a particular situation and cannot anticipate the outcome, might seek help in the form of a tarot card reader or psychic.
Tarot card reading is thought to have come into existence in the late 1700's, although it is unclear who actually put the first deck of tarot cards together. There is evidence to show that a Catholic Priest who goes by the name of Eliphas Levi came up with the concept of tarot card reading and it is the same concept that has continued on throughout the ages. Tarot card reading is used to help make sense of nonsense so to speak.
