Tarot
The Tarot is more than a deck of cards, it is a tool for our evolution. Although it was born in the 14th century, its diffusion had to wait until the invention of the printing press. And its use as a divinatory method became popular in the 18th century.
Historically, the first news about its use in divination comes from a manuscript by an unknown author around 1750, where it talks about the different meanings of the cards.
Tarot, besides being a card game and a method of divination, is an impressive tool for our evolution, if properly combined with kabbalah.
It consists of 78 cards, 22 major arcana (like the 22 letters of the Hebrew alphabet), and 56 minor arcana. It shows us the way on our tree of life, and directs us along the right paths for our growth. The Tarot represents the archetypal forces of nature, is a powerful tool for our self-knowledge, for use as a therapeutic tool, for understanding the depths of our mind, for our spiritual growth, and in some ways is a different representation of the tree of life, perhaps more accessible given its vast symbolism.
Be that as it may, the tarot is one of the best and simplest ways to approach spirituality and our inner growth.
