In this wonderful מאמר, based on a מאמר of the רבי מהר"ש, the רבי uncovers a beautiful depth hiding within the fulfillment of מצות.

Whereas מצות are likened to the "קידושין" (betrothal) stage of a relationship, and תורה to the "נישואין" (marriage) stage, it is possible to view מצות as merely a preparation for learning תורה.

However, the רבי מהר"ש explains, Hashem is betrothing us with the fulfillment of מצות, because מצות are valuable; מצות are the source of life.

This leads the רבי to uncover that truthfully, מצות too provide us with a romantic, deep connection to Hashem (albeit not on the same ultimate level of depth that תורה does)!

When we fulfill a מצוה, we are not only keeping ourselves untainted and pure, designated for Hashem. We are also inviting Hashem into our psyche, transforming ourselves and becoming better people!
