This Shabbat (3 Tammuz) coincides with the 24th yahrzeit of the Lubavitcher Rebbe,
a profound student and teacher of Kabbalah, in additional to his many better known (and probably more important!) accomplishments.
In deepest respect, the entire issue features a variety of teachings either by him (in translation: #1-4) quoting him (#5) or about him (#6,7).
At the same time, articles #3-6 focus on the rebellion of Korach and his faction against the leadership of Moses and Aaron, the main topic of this week's Reading.
