On the Ethics of Selective Observance:

What the Torah's Word for "Heel" Reveals About Partial Commitment

Parshas Eikev takes its name from a word that means heel, and Rav Kalatsky opens by explaining why: the Torah is addressing those commandments a person is inclined to trample underfoot, precisely because their apparent minor stature invites neglect. To observe them fully, the tradition teaches, is to receive blessing withheld from no one, in its complete measure.

The deeper question is what licenses a person to rank one commandment above another in the first place. Rav Kalatsky argues that any such hierarchy rests on human judgment alone, a judgment with no genuine claim to the commandment's true worth, since that worth is not ours to assess. The consequence extends further than the neglected commandment itself: once self-interest governs which obligations a person keeps, that same self-interest attaches itself to the ones he does observe, compromising even his most devoted acts. It is precisely this fear, Rav Kalatsky notes, that King David gives voice to when he speaks of the day of judgment.

The shiur closes with an account of Rav Aharon Kotler, who ordered new stationery for his yeshiva upon discovering that a printer, in the interest of a more appealing image, had added foliage to a photograph of a building where none existed. Truth, Rav Kalatsky observes, admits no partial measure, not even in service of an otherwise worthy end.

Why the Number Six Shows Up Everywhere in This Week's Torah Portion — And What It's Trying to Tell You

Continuing in Parshas Vaetchanan, Rav Kalatsky notices a pattern that keeps repeating: the number six. The declaration that nothing exists besides God appears six times in the Torah, paired six times with a phrase naming Him master of the earth. He connects this to Adam, created on the sixth day as a single individual, so that every person could say the world was created for him alone, a teaching invoked in Jewish law when witnesses testify in a capital case, to impress on them the weight of taking one life.

From there, the shiur turns to a harder question. The Talmud contains statements, like references to mermaids, that are factually false. Doesn't that undermine it? Rav Kalatsky cites a teaching that answers no: alongside its plain legal content, the Talmud also carries a hidden, esoteric layer, historically passed down orally to select students. Once it had to be written down, the rabbis used facts accepted as true in their era as a kind of code, concealing that deeper layer from casual readers. The Talmud, in short, was never meant as a science text. As Rav Kalatsky closes, the same principle applies to daily life: outcomes trace back to God's will, not to the natural process that seems to produce them.

Why Freedom From Responsibility Isn't Peace: A Lesson on Purpose and Preparation from the Duties of the Heart

This installment turns from the weekly Torah portion to the classic medieval ethical work known as Duties of the Heart, chapter four, on trust in God. Rav Kalatsky opens with the book's account of an ascetic community whose members dressed identically to erase visible class distinction, and each kept an open grave beside his own front door as a standing reminder of mortality.

The community also lived apart from wives and children, close enough to meet family obligations but far enough to avoid distraction. A modern listener might expect that arrangement, or the constant awareness of death, to produce anxiety. Rav Kalatsky contrasts it with the opposite case: refugees fleeing wartime violence, who carried no responsibility to anyone, yet had no peace of mind at all, consumed instead by raw fear for their survival.

The difference, he argues, is purpose. Tranquility doesn't come from having fewer obligations. It comes from knowing what those obligations are for. When a listener objects that organizing a life around death sounds morbid, Rav Kalatsky reframes it: preparing for what he calls "checkout time" is no different from working toward any deadline. It's what gives achievement its stakes.
