In today’s “Random Torah” we take a look at a famous Gemara in Masechet Shabbat. Here, the Gemara speaks about a period in the life of Rabbi Shimon Bar Yochai – the accepted author of the Zohar. Rashbi was forced into exile by the Roman government at the time, and in his effort to hide from them, hid away together with his son Elazar in a cave for 12 years. When he emerged, he was an even greater man than he was before – save for one area which he did not excel in. He had lost touch with reality. The reality of this world.
