Jewish Kabbalists originally developed their own transmission of sacred texts within the realm of Jewish tradition and often use classical Jewish scriptures to explain and demonstrate its mystical teachings. These teachings are held by followers in Judaism 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. One of the fundamental kabbalistic texts, the "Zohar", was first published in the 13th century, and the almost universal form adhered to in modern Judaism is Lurianic Kabbalah.
