We don’t learn Torah to gain knowledge—not even divine knowledge. At the time you are learning Torah, your mind itself is divine.

Your mind wraps itself in divine modalities. Your soul twirls and rises in a divine dance. As you wrestle with divine words, pathways and wisdom, you merge with them, so that your entire being becomes Torah.

We learn Torah because it is a mitzvah—the mitzvah of merging your mind with the mind of G‑d.

Tanya, Chapter 5.
