Under the Talis

The Rebbe records in his diary of 1932 that his father-in-law and predecessor, Rabbi Yosef Yitzchak of Lubavitch, instructed him to don four pairs of Tefillin every day. Rabbi Yisroel Gordon was a student in 770 when the Rebbe arrived in America in June, 1941. He recalls how this secret first became known to American Chassidim.
