Today's letter addresses a fundamental question: if the whole goal of Judaism is action, why is there so much theoretical and philosophical material in the Torah? And why do the Ten Commandments begin with a theological statement of truth, instead of some call to action?

In honor of 20 Av, a letter by the Rebbe's father, R. Levi Yitzchok. This letter contains precisely 101 words, and meant so much to Reb Levik that, in a subsequent letter, he asked the Rebbe to "safeguard it at all times" and described it as "written from the depths of my heart and soul".

The women who danced in the vineyards on Tu B'Av extolled the virtues of "Fear of Heaven" above all else. Here's what modern men and women can learn from their example.

Although the Talmud gives many historical reasons for celebrating 15 Av, the Rebbe emphasizes one essence of the day: recommitting to dedicated, focused Torah study and performance of Mitzvos with Hiddur.

In honor of Tisha B'Av, a Special Episode featuring two letters from the Rebbe on Nichum Aveilim—the first, with a class approach from the Alter Rebbe, Mittler Rebbe, and Tzemach Tzedek, and the second with a very novel approach from our Rebbe.

We continue our exploration of unique takes on the classic Maamar, with letters suggesting that learning Kuntres Heichaltzu can help solve marriage problems, remind us to judge others favorably, emphasize the power of group resolutions and Mitzvos, and (perhaps) help win court cases.

We begin to explore the Rebbe's unique takes on the classic Maamar, with letters suggesting that learning Kuntres Heichaltzu can help promote (and even solve) community strife, as well as influence our devotion to prayer.

When we pray for better health or write a Pan to the Rebbe, we have the custom to use the mother's name instead of the father's name. In today's letter the Rebbe strengthens the custom, and brings sources to support it.

The Rebbe's view on surgical procedures: When to listen to the surgeon; When to look for a second (or third) opinion; What types of surgeries to avoid; When to schedule an inpatient procedure.

Special Episode: What is the relationship between Tikun HaMiddos and Chassidus? Is the point of Chassidus to help me become a better person? Can Chassidus be used to fix base Middos, or is decency a prerequisite? This class looks at letters from the Rebbe and Previous Rebbe to address these questions (and resolve apparent contradictions).
