Our souls are not hungry for fame, comfort, wealth, or power. Our souls are hungry for meaning, for the sense that we have figured out how to live so that our lives matter.
When your life is filled with the desire to see the holiness in everyday life, something magical happens: Ordinary life becomes extraordinary, and the very process of life begins to nourish your soul.
Everything that God created is potentially holy, and our task as humans is to find that holiness in seemingly unholy situations. When we can do this, we will have learned to nurture our souls.
The soul is not a physical entity, but instead refers to everything about us that is not physical - our values, memories, identity, sense of humor. Since the soul represents the parts of the human being that are not physical, it cannot get sick, it cannot die, it cannot disappear. In short, the soul is immortal.
You nourish your soul by fulfilling your destiny.
There seems to be something in the human soul that causes us to think less of ourselves every time we do something wrong... And maybe it is good for us to feel that way. It may make us more sensitive to what we do wrong and move us to repent and grow.
If we put our soul into our work, if, rather than just going through the motions, what we do flows from the deepest part of our being, then after a burst of creativity, we need to replenish our souls.
