Carl Jung, the founding father of Individuation, mentioned the significance of Tarot in one of his renowned speeches in 1993.
“They are psychological images, symbols with which one plays, as the unconscious seems to play with its contents. They combine in certain ways, and the different combinations correspond to the playful development of events in the history of mankind. The original cards of the Tarot consist of the ordinary cards, the king, the queen, the knight, the ace, etc.,—only the figures are somewhat different—and besides, there are twenty-one cards upon which are symbols, or pictures of symbolical situations. For example, the symbol of the sun, or the symbol of the man hung up by the feet, or the tower struck by lightning, or the wheel of fortune, and so on. Those are sort of archetypal ideas, of a differentiated nature, which mingle with the ordinary constituents of the flow of the unconscious, and therefore it is applicable for an intuitive method that has the purpose of understanding the flow of life, possibly even predicting future events, at all events lending itself to the reading of the conditions of the present moment."
