Wisdom Creates Nature, and Wisdom Can Reshape It
Hashem made the natural world with wisdom, so a person with wisdom can restore and reshape his own nature.
In the opening verse of the Torah the Degel finds a hint in the word Elokim, whose numerical value equals that of hateva, nature. And reishis, the beginning, is chochmah, wisdom, as the Targum Yerushalmi renders it. So Hashem formed the natural order with wisdom. The body is made of four elements, and health depends on their even balance. When one overtakes the rest, weakness follows, and all healing seeks to restore the balance. Man, too, is given wisdom, and therefore he can remake his own nature. Someone born with a quick temper or a hunger for luxuries can, with understanding, grow patient and content, because a created being should resemble his Creator. The Torah is called wisdom as well, so through Torah a person's body and soul can come back into harmony. Tzaddikim, who cling to that wisdom, can even change nature for good.

The Degel teaches that your character is not fixed. Pick one habit that you wish were different, perhaps a short temper, impatience, or the pull to buy more than you need. Today, choose a single moment when it usually surfaces and prepare a different response in advance, such as taking a slow breath before you answer. Use your understanding rather than force. Afterward, notice how it went without judgment, and try again tomorrow. Real change, like nature itself, is built with wisdom and patience.
