work at a hospital and, some days, I am unable to wear tefillin during the day, but only pre-dawn. May I then put on tefillin before its regular time? [Our staff knows the querier.]
Taken together, Tefila, Teshuva & Tzedaka are the instruments which allow us to operate on our damaged souls & repair them, the tools with which we can rebuild – our holy relationship with Hashem.
