TALLIT AND TEFILLIN The mitzva of tzitzit, placing tassels on the corner of our garments, is to recall us constantly to our vocation: “Thus you will be reminded to keep all My commandments, and be holy to your God” (Num. 15:40). Over the course of time, the fulfillment of this commandment took two different forms: the tallit, worn as a robe during prayer, over our clothes, and the tallit katan, worn as an undergarment beneath our outer clothes. Though they fulfill a single commandment, they were deemed so different as to warrant two different blessings.
