Or cabbala; Ancient esoteric Jewish mystical tradition of philosophy containing strong elements of pantheism, yet akin to neoplatonism. Kabbalistic writing reached its peak between the 13th and 16th centuries. It is largely rejected by current Judaic thought as medieval superstition, but is basic to the Hasid sect.
Among its earliest documents are the Sefir Jezirah/The Book of Creation, attributed to Rabbi Akiba (died 120). The Zohar/Book of Light was written in Aramaic in about the 13th century.
