Hasidic philosophy or Hasidism (Hebrew: חסידות), alternatively transliterated as Hasidut or Chassidus, consists of the teachings of the Hasidic movement, which are the teachings of the Hasidic Rebbes, often in the form of commentary on the Torah (the Five books of Moses) and Kabbalah (Jewish mysticisim). Hasidism deals with a range of spiritual concepts such as God, the soul, and the Torah, dealing with esoteric matters but often making them understandable, applicable and finding practical expressions.
With the spread of Hasidism throughout Ukraine, Galicia, Poland, and Russia, divergent schools emerged within Hasidism. Some schools place more stress on intellectual understanding of the Divine, others on the emotional connection with the Divine. Some schools stress specific traits or exhibit behavior not common to other schools.
Etymologically, the term, "hasid" is a title used for various pious individuals and by various Jewish groups since Biblical times, and an earlier movement, the Hasidei Ashkenaz of medieval Germany was also called by this name. Today, the terms hasidut and hasid generally connote Hasidic philosophy and the followers of the Hasidic movement.
Hasidic philosophy begins with the teachings of Rabbi Yisroel ben Eliezer known as the Baal Shem Tov and his successors (most notably Rabbi Dov Ber the Maggid of Mezeritch and his students). These teachings consist of new interpretations of Judaism, but are especially built upon the Jewish mystical tradition, the Kabbalah. While the Jewish mystical tradition had long been reserved for a scholarly elite, Hasidic teachings are unique in their popular access, being aimed at the masses. Hasidism is thought to be a union of three different currents in Judaism: 1) Jewish law or halacha; 2) Jewish legend and saying, the aggadah; and 3) Jewish mysticism, the Kabbalah. Hasidic teachings, often termed exegesis, are seen as having a similar method to that of the Midrash (the rabbinic homiletic literature). Hasidic exegesis differs from Kabbalistic schools as it focuses somewhat less on the sefirot and partzufim and more on binary types of oppositions (e.g. body and soul). On the other hand, Louis Jacobs stated that Hasidic teachings should not be described as 'exegesis' as during the course of interpretation texts are taken completely out of context to yield desired conclusions, grammar and syntax are ignored, and ideas are read into the texts that they cannot possibly mean.
