The greatest wish of people of thought and broad vision and sound understanding is the oneness and unity of humanity. This reality was not so apparent in former times but in this enlightened age which is the age of science and the progress of the world of humanity, this important fact has become manifest through the help and assistance of God: that all peoples are related, that all are from one family, citizens of one country and one world. This is the century of the oneness of the world of humanity and of the decline and abrogation of the superstitions of past ages. Every learned person is persuaded that this is the century for oneness and unity and the time for fanciful prejudices to fade away. We pray that misunderstandings among nations may disappear completely so that it may be evident that the foundation of all divine principles is the oneness of mankind and that the real purpose of all divine Manifestations has been to educate humanity.
