 Israel ben Eliezer Baal Shem Tov (1698–1760), founder of Hasidism in the area of the Ukraine, spread teachings based on Lurianic Kabbalah, but adapted to a different aim of immediate psychological perception of Divine Omnipresence amidst the mundane.The emotional, ecstatic fervour of early Hasidism developed from previous Nistarim circles of mystical activity, but instead sought communal revival of the common folk by reframing Judaism around the central principle of devekut (mystical cleaving to God) for all.This new approach turned formerly esoteric elite kabbalistic theory into a popular social mysticism movement for the first time, with its own doctrines, classic texts, teachings and customs.
