QABALAH · LESSON 4 OF 8 · 15 MIN
The Four Worlds & the Parts of the Soul
Atziluth, Briah, Yetzirah and Assiah; the four letters of the Name; and the soul from Nephesh to Yechidah.
The Tree of Life is not one diagram but four, stacked like the floors of a tower. The idea that reality unfolds through four worlds grew up in medieval Kabbalah and was systematised in the 16th century; the Golden Dawn made it the key to its whole system of correspondences.
