Eating with the Intent to Study and Pray Refines the Food
With this understanding, we can explain the deeper significance of eating with our 32 teeth in a way that we can all comprehend. Eating is designed to separate the waste from the essential, nourishing food, and to clarify the sparks of kedushah from the klipos. Thus, we fulfill the ruling in the Shulchan Aruch cited above: All pleasure and benefit a person enjoys in this world should not be intended for one’s own personal pleasure but rather should be for the purpose of serving the Almighty. As it is written: “In all your endeavors know (emulate) Him.”
Thus, when a person eats and chews the food with his 32 teeth, he should have the following in mind: Chewing with the upper 16 teeth should provide the fortitude to study Torah. This alludes to the established practice to call 16 men up to the Torah each week to connect Yisrael with the Torah. It also expresses one’s intense desire to be connected through the Torah. Similarly, chewing with the 16 lower teeth should prepare us to serve Hashem through tefilah, which our sages instituted to correspond to the 16 weekly korban Tamids.
With this exalted focus and intent, the two sets of 16 teeth combine to represent the 32 “paths of chochmah,” with which the world was created. In the words of David HaMelech (Tehillim 104, 24): "מה רבו מעשיך ה' כולם בחכמה עשית"—how abundant are Your works, Hashem! You made them all with chochmah. In other words, You created and established all of creation with Your supreme wisdom, so that mankind would possess the capacity to refine everything that he eats—to separate out the refuse and extract the sparks of kedushah from the klipos. Thus, they ascend to Hashem like an aromatic, pleasing korban.
