Rabbi Yitzchak from the Zohar
Rabbi Yitzchak from the Zohar was one of the main students of Rabbi Shimon Bar Yochai and is often quoted throughout the Zohar. He was one of the six students to survive the gathering of the Idra Rabba. When the angel of death came to take Rebbe Yitzchak from this world, his teacher Rebbe Shimon saved him through his prayers accepting upon himself as a grantor on his life. Rabbi Yitzchock passed away on the same day as his teacher, on Lag Baomer the 18th of Iyyar and was buried in Wadi Amud underneath Tzfat.
