"The soul benefits from the spiritual element of the food, and the body benefits from the physical element of the food, and it is through this very mechanism, food, that they are brought together."
That's an amazing revelation. (Here I am trying to learn more halachah, but it's the secrets incidentally revealed in the halachah that speak to me the most)
[Of note: this sounds similar to the Noam Elimelech's comment that the whole purpose of this world is to eat.]
If we reexamine eating from this perspective, it can change our entire world. What we eat affects how, when, and if our souls are bound to our bodies and vice versa. It also tells us that the secret in allowing the soul to reign over the body begins and ends with which food we eat and how we consume it.
Be aware of what you eat and how it affects you; especially how it affects your service of God.
At the very least, be careful about making the appropriate berachot before and after whatever you eat, even that deceptively simple step can be enough to give you a new dimension to your spirituality you never knew existed.
