Kabbalah
Kabbalah is an ancient and mystical Hebrew method that uses configurations of numbers and symbols to define the nature of God, the universe, and the human being.
Kabbalah is Hebrew for “collection” or “receiving.”
The Book of Creation (Sefer Yezira), written by a third-century Jewish neo-Pythagorean, is believed to be the oldest known book written about Kabbalah.
The followers of Kabbalah believe that Kabbalah is a necessary part of study of Torah.
Kabbalah has also been used in some Christian churches.
Kabbalah is also spelled as cabala, Kabala, kabbala, qabala, or qabalah.
