The rich is firmly attached to wordly things, they would rather sink with their gold than let it go. The monk that you've described is attached to his self by training it with sophisticated hardships. He hoards inner peace just like the rich hoards gold. Both are practicing the culture of personality. They need to leave that baggage behind, their self-centered life and their polished personas, and reorient their life around helping others. Once they do this, an enormous internal conflict will emerge - the struggle between their selfish and selfless sides, and at the end of this path they'll enter the kingdom of God.

Those who want to climb to the mountain top need to leave everything behind. The higher they climb, the longer will be the fall if they look back for a moment and slip on this narrow path, longing for what they left behind.
