Desires themselves aren’t the problem. They’re part of being human. We naturally want things like life, food, knowledge, and connection with others. These are normal and even necessary. The issue is that, in both the natural, unspiritu person and even in someone who is only partly spiritually formed, these desires often aren’t properly guided or kept in check by a deeper love for God. Instead, they grow beyond healthy limits. They become self-centered, excessive, and sometimes even harmful — so much so that they can take control of a person’s entire life. When desires reach this point, they bring with them a constant sense of restlessness and inner turmoil. That’s why they need to be carefully guarded against.
