This is the first-ever English-language edition of the book Leo Tolstoy considered to be his most important contribution to humanity, the work of his life's last years. Widely read in pre-revolutionary Russia, banned and forgotten under Communism, and recently rediscovered to great excitement, A Calendar of Wisdom is a day-by-day guide that illuminates the path of a life worth living with a brightness undimmed by time. Unjustly censored for nearly a century, it deserves to be placed with the few books in our history that will never cease teaching us the essence of what is important in this world.
