Ein Sof

Infinite, unknowable aspect of God

Ein Sof, or Eyn Sof (Hebrew: אֵין סוֹף ʾēn sōf; meaning "infinite", lit. '(There is) no end'), in Kabbalah, is understood as God before any self-manifestation in the production of any spiritual realm, probably derived from Solomon ibn Gabirol's (c. 1021 – c. 1070) term, "the Endless One" (שֶׁאֵין לוֹ תִּקְלָה, šeʾēn lo tiqlā). Ein Sof may be translated as "unending", "(there is) no end", or infinity. It was first used by Azriel of Gerona (c. 1160 – c. 1238), who shared the Neoplatonic belief that God can have no desire, thought, word, or action, emphasized by the negation of any attribute.
