The Tree of Life and Kabbalah

Kabbalah, Cabala, Qabalah, or Mekubba is a method or discipline, a school of esoteric thought originating from Jewish mysticism. Its definition varies according to tradition and the objectives of those who follow it, from its origins in medieval Judaism to its later adaptations in Western esotericism, which defines it as Christian Kabbalah and Hermetic Kabbalah, distinguishing it from Jewish Kabbalah, which they consider a set of esoteric teachings meant to explain the relationship between the eternal and immutable God (Ein Sof, "The Infinite") and the mortal and finite universe created by the Christian God. Today, this discipline constitutes the foundation of mystical religious interpretations within Judaism.
In any case, it is a fascinating ancient philosophy.
