A compilation of major communications Shoghi Effendi addressed to the Baha'is of the world, the messages in this volume reveal a shift in emphasis from the needs or activities of national Baha'i bodies to the activities of a maturing Baha'i world community. The compilation documents unprecedented achievements on a worldwide scale and chronicles "a period of prodigious expansion and consolidation." The messages represent the culmination of decades of guidance from Shoghi Effendi and mark the last phase of the first "epoch" of Abdu'l-Baha's Divine Plan.
