What is happiness? What's the point of living the way I do, day in and day out? Twenty-five hundred years ago, in his youth, Buddha (Shakyamuni) had the same nagging questions that we do today. He never avoided them or gave up the search for answers, but devoted himself earnestly to discovering the meaning of life. That search is the starting point of Buddhism. Precisely because he agonized more than others, Buddha also attained a happiness greater than that of anyone else. In our desire to live with strength and good cheer, the life of Buddha is sure to provide invaluable insight.
Winner of the 1979 Nobel Peace Prize, Mother Teresa devoted herself to help the poor. Answering a calling from God, she opened a home in Calcutta, India, where she and her fellow nuns took in and cared for dying and desperate Indians. Even after her death, many still continue her never ending quest of providing for the basic needs of human beings.
With a population of over 14 million, Kolkata (Calcutta) is the third largest city in India. Of that 15 million, over four hundred thousand people live on the streets. In the poorest neighborhood of Kolkata, a Catholic nun from Macedonia named Mother Teresa gave love and a helping hand to the people who lived there. This is the story of a remarkable woman who devoted her life to the poor in a land far from her birthplace and inspired the entire world: Mother Teresa, recipient of the 1979 Nobel Peace Prize.
