The wisdom of Kabbalah was hidden for thousands of years, providing fertile ground for the springing of diverse theories as to its essence. All of them were incorrect. Today, the study of authentic Kabbalah is open to all, without any restrictions or prerequisites. However, it is important to know that the wisdom of Kabbalah engages only with man’s correction.
“This wisdom is no more and no less than a sequence of roots, which hang down by way of cause and consequence, by fixed, determined rules, interweaving to a single, exalted goal described as “the revelation of His Godliness to His creatures in this world. ...the whole of humanity is obligated to eventually come to this immense evolvement.”
(Baal HaSulam, “The Essence of the Wisdom of Kabbalah”)
