The Cause of God is like a house. As long as man has not entered therein he does not know what it contains. In the house there are many precious jewels, many rare objects the like of which cannot be found anywhere in this world. But the men in the street may pass by the house a 1000 times and know nothing about it. Only the one who has the key can enter. That key is the love of God.
