Mother Teresa was born in Yugoslavia in 1910, to Albanian parents. At 18 she joined a congregation of sisters in Calcutta, and in 1948 took a new congregation on the streets of the city, caring for the poor. Six years later she opened her first home for the dying. Brother Roger settled in the French village of Taize during World War II, and gave shelter to political refugees, notably Jews. The community that grew up has, since 1957, hosted meetings of young people every summer, and at the end of each year there is a meeting in a European city. Both Mother Teresa and Brother Roger always stress the importance of prayer in their personal lives, and in the building of their ministries of peace and care. In the twelve chapters of this book, each written half by one and half by the other, they set out to convey the meaning of prayer, and to express the joy they have found in this relationship with God. They describe it as a silent language, in which the heart of humankind is opened to the heart of God.
