Tefillah is such a significant part of our lives. 1 Yet, it contains a paradox – on the one hand, the times we pray and the words we say are prescribed by halakha. On the other hand, tefillah is meant to be heartfelt and filled with kavanah. How does one approach such standardized devotion while retaining continuous intention? The sources of the mitzvah of tefillah reflect this tension and offer some potential insight into this dilemma.
