Rebbe Chiya was one of the main students of Rabbi Shimon Bar Yochai and is often mentioned in the Zohar. He participated in both the Idra Rabba and Idra Zuta. After the passing of Rebbe Shimon, Rebbe Chiya fasted two sets of 40 days to see him. He was shown a vision where he entered the Rashbi's academy on high and saw the Moshiach.
