There is an ancient story that a king wanted to grant a dervish his desire. And the desire of the dervish was to fill his cup with gold coins. The king thought that it would be the easiest thing in the world to fill the cup of the dervish; but when they tried to fill it it proved to be a magic cup: it would not fill. The more money was poured into it, the emptier it became. And the king was very disappointed and disheartened at the thought that this cup could not be filled. The dervish said, "Your Majesty, if you cannot fill my cup you only have to say so, and I shall take my cup back. I am a dervish, and I will go, and I will only think that you have not kept your word." The sovereign, with every good intention, with all his generosity, and with all his treasures could not fill that cup. And he asked, "Dervish, tell me what secret you have in this cup; it does not seem to be natural. There is some magic about it; tell me what is its secret." The dervish answered, "Yes, your Majesty, what you have found out is true; it is a magic cup. But it is the cup of every heart. It is the heart of man, which is never content. Fill it with whatever you may, with wealth, with attention, with love, with knowledge, with all there is. It will never fill, for it is not meant to be filled. Not knowing this secret of life man goes on in pursuit of every object, or any object he has before him, continually. And the more he gets the more he wants, and the cup of his desire is never filled.'
