The last major letter to the American Baha'i community from Shoghi Effendi, 21 September 1957, shortly before his passing in 1957. Dire warnings about the condition of the world and exhortations from the Head of the Baha'i Faith for the Friends, in America particularly, to put their shoulder to the wheel and work harder to bring about the consciousness of the oneness and wholeness of the human race before catastrophe comes.
