Broken From Within
A power is broken by its own likeness, as Ovadiah the Edomite convert was sent to prophesy against Edom.
When Avraham sent Eliezer to find a wife for Yitzchak, he made him swear not to take a wife from the daughters of Canaan, but to go to Avraham's own land. The Noam Elimelech asks why Canaan needed mentioning at all; Avraham could simply have said, go to my family and take a wife from there. He answers with a principle: whatever a person wishes to break, he must break with its own likeness, from within. So we find with Ovadiah HaNavi, who prophesied against Edom. Chazal teach that he was a convert from Edom, and Hashem said: from them I will bring it upon them; the handle of the axe comes from the forest itself. This was Avraham's intention. Eliezer was himself a servant from Canaan, and Avraham wanted Canaan's power broken by one of its own.

The forest supplies the handle of the axe that cuts it. Many struggles can be met with the very strength hidden inside them. This week, name one trait that trips you up, such as stubbornness, impatience or a sharp tongue. Then find one place to use the same energy for good: stubbornness to keep a daily seder, impatience to hurry to a mitzvah, a sharp tongue to defend someone who is being put down. Use it once, on purpose, and see what changes.
