 However, Kabbalah limits the effect of "Yeridat ha-dorot" only to "nigleh".In contrast, the "Concealed" ("nistar") aspects of Torah, embodied in Jewish mysticism, are identified with an opposite process of successively higher articulations of mystical thought as the process of history unfolds.The reasoning for this derives from the notion that Jewish mysticism progresses instead from successive new divine revelations to supreme mystics, as the only way to deepen its conceptual structures.
