Ohr (Hebrew: אור, romanized: ʾor, lit. 'Light', plural: אורות ʾoroṯ) is a central Kabbalistic term in Jewish mysticism. The analogy to physical light describes divine emanations. Shefa "flow" (שפע šep̄aʿ) and its derivative, hashpaʾa "influence" (השפעה hašpāʿā), are sometimes alternatively used in Kabbalah and medieval Jewish philosophy to mean divine influence, while the Kabbalists favour ʾor because its numerical value equals ר״ז, a homonym for רז rāz "mystery". ʾOr is one of the two main Kabbalistic metaphors for understanding God, along with the other metaphor of the human soul-body relationship for the sefirot.
