What is a mitzvah?
An act of uniting heaven and earth.
But heaven is spiritual and earth is material. To make spirit and matter one is impossible!
A creature of earth cannot make earth heaven. And a heavenly being cannot bring heaven to earth.
But for you, it is not impossible.
This mitzvah that I am commanding you today is not impossible for you. It’s not even distant. It’s very close to you, in your mouth and in your heart to do it. (Deut. 30:11)
It is close to you because the Torah was given to you both written and orally. (Rashi)
Because within you breathes the Creator of both heaven and earth.
So that when you speak the words of His written Torah, you bring heaven down to earth.
And when you explain the words of His oral Torah, you bring earth up to heaven.
Indeed, you accomplish the impossible every day.

Shabbat Shalom 🌹
Bringing heaven down to earth, and bringing earth up to heaven through articulation of language(s) through sound and speech is really beyond phenomenal, and here's why?
Shabbat 88b and Shemoth Rabbah states when GD gave the Ten Commandments at Mt. Sinai, He spoke in 70 languages so that every nation could hear and understand the revelation! The Mishnah (Sotah 7:5) tells us that when the Jews crossed over into the Promise Land, they engraved the words of Torah in 70 languages at Mt. Ebal so all the world could read it! But what is incredible is how 4 legged beasts such as dogs can't speak, but they can understand what is being said through: voice recognition, sounds, patterns, cues, and tones. Some pet owners have even taught their pets to recognize biblical scriptures, and to put their paws together and pray! :D
When we do mitzvahs, GD partner with us to accomplish the impossible - miracles!
GD leaves no one, nor no thing out of His plans.
