Alongside the legal tradition of the Talmud, Judaism has always had a mystical stream — a tradition of seekers who wanted not just to obey God but to experience God directly.
The Kabbalah (literally "received tradition") emerged as a distinct movement in 12th-century Provence and Spain, though its practitioners claimed roots going back to Moses. Its central text, the Zohar ("Book of Splendor"), appeared in the late 13th century and is attributed to the 2nd-century sage Rabbi Shimon bar Yochai.
Kabbalistic thought teaches that God is both infinitely transcendent (Ein Sof — "without end") and intimately present in every particle of creation. Between the infinite God and the finite world are ten Sefirot — divine attributes or emanations through which God creates and sustains reality.
The most powerful Kabbalistic concept for the modern world is Tikkun — repair. The Kabbalists taught that divine sparks of holiness are scattered throughout creation, trapped in shells of darkness. Every good deed, every act of justice, every moment of genuine compassion liberates a spark and brings the world closer to its original wholeness.
This is Judaism's deepest answer to the question of meaning: you are here to gather the scattered light.
