It is very important to know what order to observe in battle, and not randomly or superficially, as many do to their detriment. The order to follow in fighting your enemies and wicked inclinations is this: entering into your heart, make a diligent examination of the kinds of thoughts and affections that surround it. Determine which passion holds highest sway and rules tyrannically in your heart. First take up arms and engage in battle against this enemy.

If other foes should assault you, continue to do battle against the one that at that moment is closest to you and wages war on you, but returning later to the initial assault.
