In the seven letters collected in this volume, Shoghi Effendi deals with issues of world order, a paramount purpose of the Baha'i Faith. Boldly and clearly, he describes the causes that have brought humanity to its present plight, presents a clear vision of the Baha'i Faith's role in human social evolution and presents Baha'u'llah's teachings that alone have the power to usher in a new era of peace and unity.
