"All Israel have a share in the World to Come". The question that arises is why it is the custom to recite the "All Israel" Mishnaic verse before [studying] Tractate Avot. The place of this Mishnaic verse is not here but in Tractate Sanhedrin, while Tractate Avot, as we know, opens with "Moses received the Torah from Sinai". We can explain this in the name of Rabbi Yaakov Yitzhak, the Seer of Lublin, of saintly blessed memory, who would whisper to himself after rising to read the Tikun Chatzot during the night, and would commune with his Creator at this time. Then, after the Tikun Chatzot, before he would begin his study of SHAS, Halachic adjudicators and Hassidism, he would ponder penitence and ask himself: What if I am one of those people about whom King David spoke, when writing Psalm 50 in the Book of Psalms, which says: "And to the wicked, God said: Who are you to recite My laws, and mouth the terms of My covenant?" … So righteous a person would say this, and declare to himself: What if he is one of those people about whom this psalm speaks? Meaning to say, what merit and what right have I to open this Talmud and learn Your Torah, Lord of the Universe? By the right of that same Mishna that is found in the tractate Sanhedrin: "All Israel have a share in the World to Come".
