1) Hell, known in Kabbalah as Klipoth, which is depicted as a reflection of the Tree of Life, below Malkuth.
2) The great void that separates the superior triangle of the Tree of Life from the remaining seven sephiroth. “We know very well that the “Great Abyss” of the eternal waters is found between Binah and Chesed. This is known by any Kabbalist who consults the Tree of Life.” - Samael Aun Weor, The Pistis Sophia Unveiled
