 In contemporary Orthodox Judaism there is dispute as to the status of the Zohar's and Isaac Luria's (the Arizal) Kabbalistic teachings.While a portion of Modern Orthodox, followers of the Dor De'ah movement, and many students of the Rambam reject Arizal's Kabbalistic teachings, as well as deny that the "Zohar" is authoritative or from Shimon bar Yohai, all three of these groups accept the existence and validity of the Talmudic "Maaseh Breishit and Maaseh Merkavah" mysticism.Their disagreement concerns whether the Kabbalistic teachings promulgated today are accurate representations of those esoteric teachings to which the Talmud refers.
