in the spring of 1967 (two days before the outbreak of the six-day war on june 3, 1967), the rebbe issued a directive to start mivtza tefillin, an international campaign by chabad hasidim to influence all male jews, regardless of their level of religious observance, to fulfill the mitzvah of tefillin (phylacteries) daily. raichik became actively involved in this, making his rounds every day in the fairfax area of los angeles where he lived, and finding jewish men who hadn't yet put on tefillin that day. he always carried tefillin, and was known for helping people put them on anywhere and everywhere, including airplanes, airports, trains, the white house, shopping malls, etc. he continued this practice until hospitalized by a stroke in december, 1997.
