The autobiographical novel by Daisaku Ikeda, president of the SGI. 1964 and 1965 are years of intense commitment for Shin'ichi Yamamoto. The young president of the Soka Gakkai begins writing the novel The Human Revolution with the aim of transmitting the spirit of his mentor Josei Toda. He also pours all his energy into raising the "young phoenixes" and developing the Seikyo Shimbun, which became a daily newspaper in 1965.
His travels continue throughout Japan and the rest of the world to encourage members and pioneers of the kosen rufu movement: the United States, France, Germany, Italy, Portugal and, for the first time, Mexico, a country that Toda had dreamed of visiting shortly before his death. Inspired by his actions, many young Japanese move abroad to boost propagation and challenge their personal destinies: kosen rufu is taking on the profile of a movement that embraces the entire world.
