זוהר שמות — דף רנד ע”ב

On the western side stands the light of Nuriel, which receives abundance and diffuses it. Life and healing descend from the eastern side where they flow forth. Four appointees stand at each face of this palace, looking toward the four sides of the world. At the center of the palace stands the holy image of a man, from whom light radiates in all directions. This palace contains purified souls and the righteous who merit the world to come.
