Tzimtzum

Tzimtzum, contraction, withdrawal, is Isaac Luria's answer to a question earlier Kabbalah had not pressed hard: if Ein Sof is infinite and leaves no place empty, where is there room for anything that is not God? The answer is that the first act of creation was not an outpouring but a retraction. God withdrew from a point within himself, leaving a vacated space, the halal panui, in which finite existence could stand, and into that space directed a measured ray of light.

How to read this divided the tradition, and the division was consequential. Taken literally, tzimtzum is an actual withdrawal, and the world occupies a space genuinely empty of the divine essence. That reading preserves God's transcendence and the substantial reality of creatures, and it was defended in the Lithuanian tradition, in the school of the Vilna Gaon and in Hayyim of Volozhin's Nefesh ha-Hayyim. Taken figuratively, the Hasidic position, stated with great force in Shneur Zalman of Liady's Tanya, the withdrawal is a concealment relative to creatures and nothing more. Nothing is empty of God, the vacated space is an appearance, and the conclusion is frankly acosmic: from God's side, creation adds nothing whatever. The eighteenth-century conflict between Hasidim and their Mitnagdic opponents turned in part on this disagreement and on what followed from it for prayer and for the status of the material world.

The term has had a long afterlife outside Kabbalah. It was taken up in Christian Kabbalah, in German idealism, and in twentieth-century theology as a model of divine self-limitation making creaturely freedom possible, Hans Jonas's post-Holocaust essay on the concept of God is among the best-known instances. Historians of Kabbalah frequently note that such uses detach the word from the cosmogonic system in which it does its work, where it is inseparable from the breaking of the vessels and from tikkun.

Gershom Scholem, the twentieth-century scholar whose work founded the modern academic study of Kabbalah, treated tzimtzum as one of the most radical ideas Judaism ever produced, precisely because of the paradox at its center: a doctrine meant to safeguard divine unity and make room for creation does so by describing an act that sounds like division and limitation, applied to a God who is supposed to admit no limitation at all.

Scholem argued that Lurianic Kabbalah as a whole, tzimtzum together with the shattering of the vessels and the ongoing work of repair, amounted to a distinctively Jewish myth of exile and restoration that mapped onto, and helped Jewish communities process, the historical trauma of the 1492 expulsion from Spain, a thesis that has been highly influential and also seriously contested by later historians who question how directly a systematic theology developed in Safed decades later reflects that specific catastrophe rather than internal developments within kabbalistic thought itself.

Scholem also proposed structural parallels between Lurianic cosmology and ancient Gnostic myths of a fall within the divine realm itself, myths Judaism had historically treated as heresy precisely because they compromised divine unity and located evil within God. The comparison prompted a considerable scholarly literature debating whether the resemblance reflects genuine historical influence, independent convergence on similar problems, or an overstatement built more on Scholem's own interpretive framework than on the primary sources.
