I think that deep-seated causes produced among many Jews a discontent and a gravitation toward mysticism. Rabbinism, which in Poland had become transformed into a system of religious formalism, no longer provided a satisfactory religious experience to many Jews. Although traditional Judaism had adopted some features of Kabbalah, it adapted them to fit its own system: it added to its own ritualism the asceticism of the "practical kabbalists" just across the eastern borders in the ancient Greek and Anatolian Jewish communities under the Ottoman Empire, who saw the essence of earthly existence only in fasting, in penance, and in spiritual sadness. Such a combination of religious practices, suitable for individuals and hermits, did not suit the bulk of the Jews. Many of these Jews would live in mountainous regions to get away from any non-Jewish influence. If you like to get together and talk about the history of our faith, let me know.
