Tanya for the 27th of Kislev כ''ז כסלו

The soul possesses three auxiliary powers, which are its instruments of expression. Like garments, they can be donned or shed at will. When the soul utilizes any of these three powers, it is “clothed” in them; when it does not use them, it is “divested” of them. Also, just as garments give expression to their wearer’s beauty and importance, so, too, when the soul dons and utilizes these “garments,” its intellect and emotion find expression.
