Tanya for the 19th of Teves, י''ט 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.
