Tanya for the 14th of Tevet י''ד טבת

In this, the twelfth chapter, the term beinoni—the “intermediate man’’ who is neither tzaddik nor rasha—will be defined. The beinoni, the Alter Rebbe explains, is one whose practical conduct in thought, speech, and action is dictated solely by the divine soul; it has the upper hand over the animal soul. The beinoni accomplishes this by not allowing himself to be dominated in any way by the animal soul, even for the shortest duration, never thinking, speaking, and surely not acting in a sinful manner. The garments of the divine soul alone—namely thought, speech, and action in Torah and mitzvot—are those used by the beinoni.
