Ben Zoma said that the strongest force of the heart's might is the power to overcome evil inclination. Courage in battle is not as great; there are many strong, brave warriors who have learned the arts of war and know how to fight. But the battle of the evil inclination demands much greater, more powerful and more sophisticated force. It [the evil inclination] lies in wait, ready to attack and destroy, and it already has a powerful grip over the body. Defeating this most formidable enemy is true heroism in battle.
