Grief that is ignored turns into depression or hopelessness. Hurt turns into cynicism, lack of trust, or worse. Anger turns into bitterness and hatred. The list goes on, but mindful people know that just as you do not want a tumor growing in your brain, you do not want one growing in your heart either. There are no benign tumors of the heart. They all spread their cancer into the visible world, where they destroy all that one is trying to build— relationships, reaching goals, happiness, and fulfillment. No matter what a person is trying to accomplish, if he is walking around with unresolved matters of the heart, their goals will be negatively affected.
