World known kabbalist Yehuda Ashlag (Baal HaSulam) provides the following definition in his article :
"The Essence of the Wisdom of Kabbalah"
This wisdom is no more and no less than a sequence of roots, which hang
down by way of cause and effect, in fixed, determined rules,
interweaving to a single, exalted goal described as, “the revelation of
His Godliness to His creatures in this world.”
