Sharing in Mother Teresa's work

One day a lady came to Mother Teresa dressed in a very expensive sari. She told Mother Teresa "Mother, I want to share in your work." Mother Teresa prayed for a moment to get the right answer to give her about sharing in her work, and she told her "I would begin with the sari. You start buying a cheaper sari each month, and the money you save, you bring it to me for the poor."

So the lady started buying cheaper saris and she told Mother Teresa that it had not only changed her life, but She really understood sharing, and the lady added that she had received much more than she had given.
