Tanya Chapter 4 part 1. You love, but are you truly realizing that love?

The Divine soul has three garments through which it finds expression: thought, speech, and deed, specifically through the 613 mitzvot of the Torah. The intellect of the Divine soul is expressed through the garment of thought, while its emotions—love and awe—manifest through the garments of speech and action. Speech and action become the expression of emotions because the true fulfillment of the mitzvot is driven by love. Fear, on the other hand, is expressed by observing the prohibitive Divine commands, which can stem from either an external fear of rebelling against Hashem's sovereignty or a deeper fear, where one feels ashamed to do anything or nurture anything that Hashem despises.
