Thank you Rabbi Schapiro for this outstanding class. It truly is the best I have heard. I have just ordered a pair of Rabbeinu Tam tefillin and will start putting them on in a few weeks. Your class really helped me to understand more deeply the significance of the mitzvah of tefillin in general, and of R. Tam specifically. I hope to take the inspiration with me as I take upon myself this new mitzvah, G-d willing with acceptance of the Heavenly yoke!
