As described in the Idra Rabba, before the Idra disjourned, three of the students died: Rabbi Yossi bar Yaakov, Rabbi Chezkiyah bar Rav, and Rabbi Yisa. As it is told, these students filled up with Godly light and therefore journeyed to the eternal world after their deaths. The remaining students saw their friends being carried away by angels. Rabbi Shimon said some words and they were calmed. He shouted out, "Perhaps, God forbid, a decree has been passed upon us to be punished, for through us has been revealed that which has not been revealed since the time Moshe stood on Mount Sinai!" At that instant a heavenly voice emerged and said, "Fortunate are you Rabbi Shimon! and fortunate is your portion and the portion of the friends who remain alive with you! For it has been revealed to you that which has not been revealed to all the upper hosts."
