The Ability of Prayer

The evil inclination does all that it can to fight and disturb us during prayer, because fulfilling this mitzvah is the most fitting way to defeat it. Hence we must concentrate on praying with all our strength. The evil inclination is ready to fight us, the Jewish people, and to prevent us from pouring out our hearts as we should during prayer. In effect, prayer has ability to “defeat it more than all the other mitzvot.” We can therefore deduce its great value and importance. – Be'er Moshe
