Talmud Bavli Shabbat on Fear as Prerequisite to Torah Knowledge

"Rabbah bar Rav Huna said: Any person who has acquired for himself Torah knowledge, but has not acquired for himself the fear of Heaven is comparable to a treasurer to whom the keys to the inner chambers have been handed, whereas the keys to the outer chambers were not handed to him. How can such a treasurer possibly gain entrance to either the inner or the outer chambers?"

-- Talmud Bavli, Shabbat 31a-b

Mishnah Yoma on Reviewing One's Torah Learning Often

It is a great virtue to review one's Torah learning regularly and consistently. It is reported that the Vilna Gaon reviewed the entire Babylonian Talmud every month (which normally takes 7.5 years by the Daf Yomi cycle), and that he reviewed the entirety of the tractates "Shabbat" and "Eruvin" every Sabbath. The word "Mishnah" means repetition, and it is especially important to verbally recite mishnayot often, so that they are always fresh in one's mind.

This virtue is brought to light in the Mishnah itself, in tractate "Yoma". This mishnah describes the preparations made by the Kohen Gadol during the week before the Yom Kippur avodah:

"They assigned the Kohen Gadol two elders from among the elders of the Sanhedrin. They would read to him from the Torah passage that describes the order of the Temple service on the Day of Atonement, and elaborate on its laws. And they would say to him: 'My master, Kohen Gadol, you should read this passage with your own mouth, in case you have forgotten, or in case you have not learned.'" -- Mishnah, Yoma 1:3.

Notice that the suggestion that the Kohen Gadol read the passages out loud, in case he forgot or didn't really learn them, is not taken an insult to the Kohen Gadol's stature. We learn from this that even the greatest Torah scholars should review their learning often and with great care.

Sefer HaZohar on Torah Study and the Tree of Life

"How intensely human beings should contemplate the service of the blessed Holy One and engage in Torah day and night!  For on everyone engaging in Torah, the blessed Holy One prides Himself above and below - since Torah is a tree of life, a tree of life for all those grasping her, extending them life in this world and in the world that is coming."

-- Sefer HaZohar, 1:107a

Talmud Bavli Succah on Torah Study in Breadth and Depth

"This is similar to the practice of Rava and Rami bar Chama.  When they would stand before Rav Chisda, they would first run through the Gemara with one another to review the material, and then analyze the material with logic."

-- Talmud Bavli, Succah 29a

This dictum encodes a formula for Torah study: breadth first, then depth.

Talmud Bavli Bava Kamma on Gentiles Studying Torah of Equal Status to High Priest

"Rabbi Meir used to say, 'Whence can we learn that even where a Gentile occupies himself with the study of the Torah he is equal in status to the High Priest? We find it stated: 'You shall observe My statues and My ordinances, which a man shall do and live by them. I am YHWH.' (Leviticus 18:5) It does not say 'priests, Levites and Israelites', but 'a man', which shows that even if a Gentile occupies himself with the study of the Torah he is equal in status to the High Priest.'"

-- Talmud Bavli, Bava Kamma 38a

Sefer haZohar on the Torah as the Name of God

"The whole of the Torah is the name of the Blessed Holy One and he who studies it is like one who studies the holy name, since the whole Torah is one holy name, a supernal name, a name that comprises names."

-- Sefer haZohar, 2:124a

Talmud Bavli Berachot on Protection Granted to Those Who Study Torah

"Rabbi Shimon ben Lakish said: Anyone who engages in Torah study, afflictions keep away from him."

-- Talmud Bavli, Berachot 5a
