The concept of Or HaGanuz (Hidden Light) is a lasting esoteric theme in Jewish theology, originating in Genesis and evolving through Midrash, Talmud, Kabbalah, and Hasidism. This article traces its development, arguing that the hidden light shifts from a cosmic phenomenon reserved for future righteous individuals to an intimate dimension of spiritual consciousness accessible through Torah study, and finally to a universal potential in every human being through maternal transmission. A radical reinterpretation is proposed: the Talmudic angel Layla, who teaches Torah in the womb, represents the archetypal mother, and every fetus possesses inherent potential for righteousness through this primordial pedagogy in gestation's darkness, which paradoxically becomes the source of hidden light.
Divine revelation in Jewish textual traditions emerges not from the text alone but from the dialectic between immanence and transcendence, law and mystical yearning. This article examines how interpretive frameworks navigate this paradox by comparing the intellectual approach of Rabbi Chaim of Volozhin, the hermeneutics of religious passion and restraint developed by the Netziv (Rabbi Naftali Zvi Yehuda Berlin), and the contemporary philosophical perspectives of Elliot Wolfson, alongside cross-cultural insights from Slavoj Žižek, Moshe Idel, Allan Nadler, and Simone Weil. The analysis illuminates tensions between transcendence and immanence, nomian structure and religious enthusiasm, and the limits of religious language in textual engagement.
