Thoughts from the Daf
As the Talmud is, at its core, an oral tradition—with the words before us a summary of “classroom”” discussion—it is not surprising that debates will occur as to what the “teacher” actually said.
The opening Mishnah of the sixth chapter of Brachot discusses the various blessings one makes on different types of food. The Talmud attempts, but is unable, to find a scriptural source that tells us that one must make a blessing before eating, finally concluding that we need no source. It is a sevarah, a simple, obvious, logical inference that one must bless G-d before we eat, as "it is forbidden to benefit from this world without a blessing". Verses in the Torah are (generally) needed only to tell us that which we would not otherwise know.
One of the exciting aspects of Talmud study is the range of ideas presented, and the openness to expressing radical ideas—including those bordering on the heretical. Even more fascinating is that the Talmud finds license for such views in the biblical texts themselves.
The Talmud spends a good deal of time discussing the proper frame of mind for prayer. In a rather obvious remark (yet, much easier said than done), the Gemarah notes that “One must aim their thoughts towards heaven” (Brachot 31a). Proof for this is provided by the great sage, Rabbi Akiva, as follows: “Rav Yehuda says this was the custom of Rabbi Akiva, when he would pray between him and himself, one would leave him in this corner and find him in a different corner”. Yet, the Gemarah seems to note that such heavenly focus is only appropriate if one is davening privately.
The Gemara, in discussing the propriety of making an “early Shabbat”, records that Rav Yirmiya davened just behind his teacher, Rav, on Friday afternoons while Rav was reciting the prayers for Shabbat. The Gemara questions how he could do so, as it was Rav himself, the founder of the great academy in Sura, who taught that it is inappropriate to daven next to or behind one’s teacher.
