165 ' word, when written down, becomes a book; a com- mand which is brought to pass becomes an action; and this is, with these believers, the meaning of the words: Run fa yakun. " (God said) ' Let it be,' and it was." The world of command is devoid of contradiction and multiplicity; it is pure in its essence; butthe world of creatures contains contradiction and multi- plicity, and no atom of all atoms of beings is out of the material world. *' There is nothing fresh or dry but in the true book (the Koran)." Besides, the world of forms and of perceptible things is to be considered as the book of God, and every thing as a Surah, " a chapter/' of the Surahs of this book; the alternation of days and nights, the changes and alterations in the horizon and in the phenomena are the vowel points of this book; the days and nights of this book, Surah after Surah, verse after verse, letter after letter, follow each other, as in writing the lines are read in succession; thus thou proceedest, from line to line and from let- ter to letter, until thou findest the meaning which is hidden in the subject of the words and expressions, until thou knowest and renderest evident to thyself the purport of the book: " We shall show our verses (of the Koran) in the horizon (every where), " and in their souls, until it become evident to them that it is the " truth."
