Zhamsaran (Peter Alexandrovich) Badmaev was the only doctor and theorist of Tibetan medicine in Russia; his activities unfolded in St. Petersburg under Alexander III, who became the godfather of the young Buryat, gained universal fame under the last Tsar Nicholas II and ended under Soviet rule in 1920 - after arrests, prisons and death. The author of the first part of the book, Badmaev's grandson, writer Boris Gusev, with documents and a family archive, talks about the life and work of his grandfather. In the second part, Peter Alexandrovich himself reveals the secrets of Tibetan medicine.
