1.  The second Sephirah of the cabalistic Tree of Life, the topmost Sephirah on the Pillar of Mercy. The term is a Hebrew word meaning "Widsom." It represents the archetype of the number 2, the masculine aspect of the Godhead. It corresponds to the divine name Yah, the archangel Raziel, the angelic choir called Ophanim (Wheels) and the Mazloth, or heavenly Sphere of the Zodiac.

2.  In Chokmah is a cloud-like grey which containeth various colours and is mixed with them, like a transparent pearl-hued mist, yet radiating withal, as if behind it there was a brilliant glory. And the Sphere of its influence is in Masloth, the Starry Heaven, wherein it disposeth the forms of things. And Yah is the Divine Ideal Wisdom, and its Archangel is Ratziel, the Prince or Princes of the knowledge of hidden and concealed things, and the name of its Order of Angels is Auphanim, the Wheels or the Whirling Forces which are also called the Order of Kerubim.
