I would like to share the following words of St. John of the Cross:
“It is true that you were created to enjoy, but to enjoy God. However, God is not present to your senses, while your “self” and the things of earth are so close to you. Hence instead of looking beyond yourself and all creation in order to reach God, instead of making use of creatures to help you rise toward the Creator, you pause and seek your happiness in them. You pause with an inordinate affection, and for this grain of satisfaction, you blind your heart to earth and become incapable of union with God, the only source of real happiness. This inordinate desire for pleasure is the thing which turns your desires and affections towards creatures, instead of fixing them on God. This is the root of every attachment, no matter how slight.”
Thanks to Chris Clody for posting it in the first place!
