Ein Sof (or Ayn Sof) (Hebrew אין סוף), in the Kabbalah, is understood as infinite divinity. Ein Sof may be translated as "no end", "unending" or Infinite (titular capitalization). Ein Sof is the divine origin of all created existence: this is in contrast to the Ein (or Ayn), which is infinite no-thingness.Scholem, Gershom, p.88 and ff, "Kabbalah" © 1974According to Gershom Scholem, Ein Sof is the emanator of the sefirot. Sefirot are energy emanations found on the Kabbalist Tree of Life. Ayn Sof, the Ancient of All Ancients emanates the sefirot into the cosmic womb of the Ein in a manner that results in the created universe.
