Channeling the Divine contains a discourse that focuses on the mitzva of tefilin and explores the mystery of how the most profound spiritual realities find expression in the very concrete act of binding boxes containing Torah parchments on one s arm and head. Composed by the Rebbe for his son s bar mitzva, the discourse has been repeated by Chabad bar mitzva boys for decades. In this discourse, the child who is turning into an adult faces the reality that very few can devote their lives entirely to the study of Torah. Nonetheless, even in the midst of worldly reality, we are given a mitzva, the mitzva of tefilin, which affects us in the same way as if we had spent all our time in study.
