Shabbat Shalom, nudniks!
The Rabbis taught: Four entered the Paradise i.e. dealt with the loftiest secrets of Torah. They were Ben Azzai, Ben Zoma, Acher and Rabbi Akiva. Rabbi Akiva said to them, "When you come to the place of pure marble stones, do not say, "Water! Water!" for it is said, "He who speaks untruths shall not stand before My eyes' (Psalms 101:7)". Ben Azzai gazed and died. Regarding him the verse states, "Precious in the eyes of G-d is the death of His pious ones" (Psalms 116:15). Ben Zoma gazed and was harmed. Regarding him the verse states, "Did you find honey? Eat as only much as you need, lest you be overfilled and vomit it" (Proverbs 25:16). Acher cut down the plantings. Rabbi Akiva entered in peace and left in peace. ---Hagigah 14b
4 entered The Paradise but only 1 came back. What does this mean?
