“In Qabalistic and Tantric traditions, the serpent winds around the central axis, the serpent of wisdom or Kundalini. Often depicted as two opposing serpents, it is necessary to awaken and balance this energy as it winds through the active and passive channels of the spine or the active and passive pillars of the Tree of Life. By activating the central axis, the Crown may be reached, which is timelessness, immortality and union with the Divine.”
