Here are two interesting stories which the Rebbe wrote in his diary in 1935.
One time, the Maggid of Mezritch summoned Reb Menachem Mendel of Horodok, Reb Pinchas and the Alter Rebbe, and presented them with a question in the revealed aspect of Torah (nigleh = Talmud). In the course of discussing the issue, Reb Zusia of Anipoli approached, and inquired what they were speaking about. Reb M”M answered that it doesn’t apply to him. In the meantime, Reb Levi Yitzchok of Berditchev entered the room, and they told him the entire issue under discussion, as Reb Zusia stood by and listened.
Reb Zusia left the room and began to cry, declaring, “Master of the universe, Zusia doesn’t have a portion in the Torah! It isn’t shayach (pertinent) to him! etc.
Later on, Reb Zusia went to the Alter Rebbe and told him that he was embarrassed [to talk about this] in front of the others, אבער בא עם לייגט זיך אזוי — but this is how I understand the issue. He then explained the entire issue.
The Alter Rebbe replied that this was “Torah from Above.” Afterwards, the Alter Rebbe told the explanation in the name of Reb Zusia to the Maggid, who accepted it.
Another story:
When the Previous Rebbe, Rabbi Yosef Y. Schneersohn, was in Vienna, someone told a story to his father, Rabbi Sholom Dov Ber Schneersohn, about Reb Meir of Premishlan, who was asked a very difficult question regarding a passage in the Rambam’s Mishneh Torah by a tremendous Torah scholar (gaon). Reb Meir said that he would answer the following day, and they set a time to reconvene.
The following day, Reb Meir learned this passage together with the great scholar, and enlightened him by explaining it. The scholar was astonished at the explanation. Sensing this, Reb Meir said, “When Reb Meir goes to the mikvah, גייט ער דורך הימעל — he goes through the heavens. [When in the heavens,] I asked them to bring me to the chamber of the Rambam, where he learned with me this very passage.
