The Jewish Secret Too Dangerous to Teach — Until Now

Send on WhatsApp Watch on YouTube Subscribe

Welcome to one of the most profound explorations in this entire series. For thousands of years, Jewish mysticism — Kabbalah — was transmitted only to a select few, in secret, from master to student in whispered chains stretching back to the prophets. Why? Because its teachings were considered spiritually explosive. A single misreading could lead someone to anthropomorphize God, abandon Jewish law entirely, or tap into forces they couldn’t control. And yet in the 16th century, something changed. The gates were deliberately opened. Kabbalah flooded into the world — not by accident, but by divine design. In this transformative class (Part 4 of our Revolutions of the Soul series), Rabbi Greenberg takes you through the full story: from Abraham’s Sefer Yetzirah to the Zohar’s centuries-long concealment, from the trauma of the Spanish Expulsion to the mystical city of Tzfat, and from the systematic brilliance of the Ramach to the staggering 2.5-year revolution of the Arizal — the man whose impact Moses would have needed 40 years to achieve. And at the heart of it all: Tzimtzum — the radical teaching that God infinitely contracted Himself, withdrawing His presence to carve out space for YOU to exist. Whether you’re new to Kabbalah or a serious student, this class will shift the foundation of how you understand God, Torah, and why you’re here.
