Kabbalists view their mystical knowledge as originating with the
revelation at Mount Sinai and thereafter being communicated
orally from master to disciple. Eventually Kabbalistic teachings
were written down. Kabbalists incorporate their own worldview
and symbols into their readings of the Bible and earlier works
of Jewish mysticism. Eventually, Kabbalists gave expression to
their traditions and practices through books. The first book of
this kind to emerge was Sefer HaBahir, the Book of Illumination.
