This Wednesday night - Thursday (3 Tammuz) coincides with the 26th yahrzeit of the Lubavitcher Rebbe,
a profound student and teacher of Kabbalah, in additional to his many better known accomplishments;
A pair of teachings from him on life in the Era of Mashiach are in the first two articles, and three more (#5-7) are from him (Balak, Avot) or about him (Story), respectively.

A much older anniversary (2469 years!) occurs two days later on Shabbat. The 5th of Tammuz is the date the prophet Ezekiel had his famous prophetic vision of the "Divine Chariot," which we read as the Haftorah portion on Shavuot and upon which certain areas of study in Kabbalah are based. Article #3 discusses what was considered a prerequisite for prophecy.
The 6th article is for the fourth chapter of Pirkei Avot, for those who continue to study it on Shabbat afternoons throughout the summer.
