Because no person can really be reduced totally and finally into a thing, people stop loving people.
They start loving things. It is more safe that way. Watch yourself. Do you love things? That means you have forgotten completely who you are and you have forgotten completely that God exists as a presence in existence. And you will never be able to have any communion with God.
Millions of people only go on gathering things, go on possessing things. Finally what happens?
They are possessed by things. If you try to possess things you will be possessed by things. And this is the ugliest state a man can fall to.
