Judaism is primarily a way of life. The 613 Mitzvos/commandments are intended to instill G-dly meaning into every facet of life. Tefillin exemplify the ultimate goal of Jewish practice. The book describes 17 different objectives of a Mitzvah and how Tefillin epitomize these goals. The book also devotes a chapter to the role of women with respect to Mitzvos in general and Tefillin in particular.
