The End of Misery

The miseries of the world cannot be cured by physical help only. Until man’s nature changes, these physical needs will always arise, and miseries will always be felt, and no amount of physical help will cure them completely. The only solution of this problem is to make mankind pure. Ignorance is the mother of all the evil and all the misery we see. Let men have light, let them be pure and spiritually strong and educated, then alone will misery cease in the world, not before. We may convert every house in the country into a charity asylum, we may fill the land with hospitals, but the misery of man will still continue to exist until man’s character changes.
