(2) The Revelation of Baha is contained in his Books and Tablets (Epistles). Some of these are the "Ikan," the "Surat ul-Haykal," the "Hidden Words," the "Seven Valleys," and the "Kitab-ul-Akdas." Remey[34] pronounces them "The latest and greatest of God's revelations to the world." "They contain knowledge which was sealed and closed up by the prophets of bygone cycles, so that the minds of the wisest of men were unable to comprehend it." Thornton Chase, exceeding the others in his extravagant language, declares that "were all the books of former days lost and forgotten, the whole of true religious teaching could be found in the 'Bahai Revelation.'" The "Kitab-ul-Akdas," "The Most Holy Book," is called by M. Abul Fazl the "greatest" and "most important." It consists of 146 pages of manuscript, about 10,000 words. It was written at Acca in Persian and Arabic. It has been translated into Russian, and a synopsis of it is given by Professor Browne,[35] of Cambridge University, in the _Journal of the Royal Asiatic Society_, 1892, of which I make use. The "Kitab-ul-Akdas" warns the learned against criticizing it, and in imitation of Mohammed challenges them to produce the like of it. It is similar in its teachings to the "Bayan" of the Bab, though less fantastic and mystical. Its contents are confused and unsystematic. It has laws--ceremonial, moral, civil, criminal--mingled with rhapsodies, exhortations, addresses, and various digressions. After an introduction and some laws, follow addresses to the Emperor of Germany and to the Sultan of Turkey, to the cities of Teheran and Kirman, and to the province of Khorasan. After more laws there is a digression about revelation; then more laws and a digression about the Bab; again sundry laws, followed by a denunciation of Subh-i-Azal, and this by various civil laws, ending with a command to select a universal language. The book is a medley, and bears internal evidence of the truth of the tradition that it was written piecemeal in answer to various questions from believers. The fragments were jumbled together without order. The learned are reminded by Baha that he never studied the sciences, and there is too abundant evidence in the book itself to confirm the statement. It ranks far below Deuteronomy as a system of laws or a literary composition.
