Tzimtzum

The tzimtzum or tsimtsum (Hebrew   "contraction/constriction/condensation") is a term used in the Lurianic Kabbalah to explain Isaac Luria's new doctrine that God began the process of creation by "contracting" his Ein Sof (infinite) light in order to allow for a "conceptual space" in which and seemingly independent realms could exist. This primordial initial contraction, forming a Khalal/Khalal Hapanui ("vacant space", חלל הפנוי) into which new creative light could beam, is denoted by general reference to the tzimtzum. In contrast to earlier, Medieval Kabbalah, this made the first creative act a concealment/Divine exile rather than unfolding revelation. This dynamic crisis-catharsis in the Divine flow is repeated throughout the Lurianic scheme.
