The Spiritual Combat

It is very important that you be aware what method to observe, in order to fight properly, and not randomly or superficially, which many people do, and consequently do great damage to themselves. The method which you ought to use to fight your enemies and your wicked inclinations is this: entering into your heart, make a diligent examination as to what sort of thoughts and affections surround it. Determine which passion most possesses and rules tyrannically in your heart. You should take up arms and engage in battle first against this enemy.

If it should occur that you be assaulted by other enemies, you should continue to fight against the one that is in that moment closer to your heart and is waging war on you, but you should return later to the initial assault.
