Mother Teresa founded the Missionaries of Charity in Kolkata, India in 1950. For some 45 years, she toiled among the poor and mentored other nuns. Much of her work was in Calcutta. Her order worked in more than 25 countries throughout the world.
One of my favorite Mother Teresa quotes comes from her book of prayers and meditations, titled A Gift for God:
Put yourself completely under the influence of Jesus, so that he may think his thoughts in your mind, do his work through your hands, for you will be all-powerful with him to strengthen you.
Mother Teresa won the Nobel Peace prize in 1979.
