Our Torah reading this week begins, “If you walk in My ordinances and fulfill My commandments…” before proceeding to list the blessings that follow. Rashi explains that “walking in My ordinances” refers to diligent Torah study, while “fulfilling My commandments” refers to performing mitzvot.

The Talmud makes a striking distinction between these two categories. Although Torah study is itself a mitzvah, it is treated differently from other mitzvot such as lighting Shabbat candles or giving tzedakah:

“A transgression extinguishes the merit of a mitzvah one performed, but a transgression does not extinguish the merit of the Torah one studied.” (BT Sotah 21a)

At first glance, the Talmud seems to establish a hierarchy of mitzvot: Torah study appears to be the most enduring and powerful, while other mitzvot are less so. Otherwise, why would a sin erase the merit of a mitzvah but leave untouched the merit of Torah study?

Rabbi Menachem Mendel Schneerson, the Lubavitcher Rebbe, offers a compelling rationale. A deed performed with minimal effort can be undone by another deed performed with minimal effort. Many mitzvot—though precious—do not require sustained exertion. A transgression, which also may require little effort, can therefore cancel out their merit. But Torah study, Rashi reminds us, demands toil, discipline, and sustained labor. Because it is achieved through deep effort, it cannot be undone by something done lightly.

This insight resonates with a modern parallel. In his 2008 book Outliers, Malcolm Gladwell—drawing on the research of psychologist K. Anders Ericsson—argues that elite performers in music, chess, and athletics typically require 10,000 hours of focused, deliberate practice to master their fields. Talent matters, but it is not enough. Mastery emerges from effort, opportunity, and support.

Gladwell’s 10,000‑hour rule highlights the transformative power of sustained effort. The Rabbis go one step further: they teach that even the beginning of that effort matters. Torah study is not powerful because it produces experts; it is powerful because it produces change. Every act of learning requires intention, discipline, and inner engagement. That is why its merit cannot be erased. It is not the quantity of hours that counts, but the quality of the self we bring to them. Torah study refines us in ways that cannot be undone.
