The intentional life cannot be ruled by obsessions. They are unsuitable candidates for ultimacy. They distract and instead of being occupied with life in its totality, obsessions get you preoccupied with some aspect of life as though it were all of life.
"For the world offers only a craving for physical pleasure, a craving for everything else we see, and pride in our achievements and possessions. These are not from the Father, but from this world." - The Bible (1 John 2:16)
