These interviews with two generations of American martial artists describe how aikido translated from Japan into an American art - integrating some American values, yet remaining an essentially Japanese cultural tradition. In addition, they reveal how aikido dramatically changed the lives of these thirteen women and men who rank among the most prominent aikidoists in the United States. "Disciples" features four individuals who trained in Japan with Founder Morihei Ueshiba, gaining insight into aikido's moral and spiritual foundations. "Teachers" focuses on three senior instructors who have disseminated different styles of aikido. "Innovators" includes martial artists whose practice and teaching integrate aikido with meditation, bodywork, conflict resolution, counseling, and philosophy - bringing centeredness and nonviolence "off the mat."
