Why should misery perpetually exist on earth, in spite of God’s infinite love and mercy?

The source of eternal bliss is the self in all. The cause of perpetual misery is the selfishness of all. As long as satisfaction is derived through selfish pursuits, misery will always exist.

Only because of the infinite love and mercy of God can man learn to realise, through the lessons of misery on earth, that inherent in him is the source of infinite bliss, and all suffering is his labor of love to unveil his own infinite self.
