It has long been known that Tarot is an excellent oracle, a means of divination which can help people find their way, to make the decisions which can help them to mold their lives and bring about the future they desire.
But, how does it work? How can these cards with the strange pictures on them actually tune in to us and help us see our life from another viewpoint and find the changes we need to
Carl Gustave Jung, famous Swiss psychiatrist and philosopher, was the first person to use the term archetype. He theorized that all human beings had, in their subconscious minds (he referred to it as the "unconscious" mind), images which had been with us since the dawn of history; images like kings and queens, lions, devils and Angels.
In human beings, these images seem to take the place of the instincts that all of the lower animals seem to have. Jung believed that it was this archetypal imagery in the Tarot which spoke to the the subcomsciousness of some sensitive people and helped them to "tune in" to others and see what might be ahead for them.
Jung also postulated that there was a Universal Law which superseded the Law of Cause and Effect. He called this the Law of "Synchronicity." Simply stated, this law says that there are certain events that happen outside of time which, although we can't find a cause and effect relationship, are meaningfully linked to other events. He believed that it is this Law that explains why just the right Tarot card comes up, at just the right time, to make the reading meaningful. However it works, Tarot has proved itself over and over, through the centuries, for millions of people in helping them to find their way.
