Serving Hashem in every way
TefillahParnassahTorah learning
Hashem wants to be served with every part of a person and in every situation. When travel or business keeps a Jew from his usual learning and davening, he should not be upset: Hashem arranged it so that he could serve Him differently, by cleaving to Him in thought and in the way he conducts himself. There is no place and no activity where avodas Hashem is impossible.
