He was a third and fourth generation Tana mentioned a number of times in the Zohar, where he is called Rabbi Cruspidi Chamid Leba. He authored a mytical Kabalistic book that was studied by Rabbi Shimon Bar Yochai and the Chavarim. At one point Rebbe Cruspidi had a 'near death experience' but was spared since he had been forgiving his entire life. In the 'other world' he witnessed the supernal courts in action and was shown the chamber of Moshiach.
