Kabbalah or Qabalah (/kəˈbɑːlə, ˈkæbələ/ kə-BAH-lə, KAB-ə-lə; Hebrew: קַבָּלָה, romanized: Qabbālā, pronounced [kabaˈla] ; lit. 'act of receiving, acceptation') is an esoteric method, discipline and school of thought in Jewish mysticism. It forms the foundation of mystical religious interpretations within Judaism. A traditional Kabbalist is called a Mekubbal (מְקֻובָּל, Məqubbāl, 'receiver').
Jewish Kabbalists originally developed transmissions of the primary texts of Kabbalah within the realm of Jewish tradition and often use classical Jewish scriptures to explain and demonstrate its mystical teachings. Kabbalists hold these teachings to define the inner meaning of both the Hebrew Bible and traditional rabbinic literature and their formerly concealed transmitted dimension, as well as to explain the significance of Jewish religious observances.
