A special centenary edition marking the 100th anniversary of the talks delivered by Abdul-Baha during his historic journey through North America in 1912. This collection of 140 talks touches on a wide range of subjects including the coming of age of the human race, the oneness and continuity of the Prophets of God, and the oneness of religion as a social force for establishing world order and peace. These talks serve as a priceless resource for studying the language and personal example of one of the most significant religious figures in recent history.
