Vaetchanan
Rabbi Schapiro on the Parshah: Va'etchanan
Asks why the source pasuk for the universal obligation to learn Torah, ושננתם לבניך, speaks specifically about teaching children, and why the Rambam opens Hilchos Talmud Torah with a father's duty to teach his child rather than the general obligation on every adult. Connects this to the fact that unlike every other mitzvah, chinuch in Torah study alone is a father's Torah-level obligation, not merely rabbinic. Explains that because Torah is Hashem's own chochma rather than an ordinary wisdom, grasping its true inner meaning demands the kind of bitul, self-nullification free of ego, that a child naturally embodies and that every adult must learn to recover.
