No one in this world is happy unless he has opened wide the gates of his spiritual Jerusalem—his soul—and received God into himself. A godless man feels lonely to despair. The society of others does not make his loneliness go away, but only increases it. However he who has taken God into his soul will never feel lonely even in a desert. No one dies an eternal death other than one in whom God has died. 

-St Nikolaj Velimirovic
