The wisdom of Kabbalah is the most ancient of all wisdoms. It goes back to the time of Abraham the Patriarch, in the 18th century BC, 3800 years ago. Abraham the Patriarch was an ordinary Bedouin tribesman in Babylon, who discovered the existence of Godliness, a reality outside this world. He then wrote a book about it called Sefer Yetzira (The Book of Creation), which is actually the very first book about the wisdom of Kabbalah.
