And a merchant said, "Speak to us of Buying and Selling." And he answered and said:

"To you the earth yields her fruit, and you shall not want if you but know how to fill your hands.

It is in exchanging the gifts of the earth that you shall find abundance and be satisfied. Yet unless the exchange be in love and kindly justice, it will but lead some to greed and others to hunger."

From "The Prophet" by Kahlil Gibran
