A. L. M. Nicolas quotes in Chapter 3 of his "Essai sur le Shaykhisme," II, p. 43, the following extract from the Sharh-i-Qasidih of Siyyid Kazim: "I have announced that every hundred years there are a chosen few who spread and sow the precepts which explain that which is lawful and that which is unlawful; who tell of the things that were hidden during the hundred preceding years. In other words, in every century a learned and perfect man is found who causes the tree of religious law to revive and bloom; who regenerates its trunk to such an extent that at last the book of Creation comes to its end in a period of twelve hundred years. At that moment, a certain number of perfect men will appear who will reveal certain very intimate things which were hidden.... Therefore, when the twelve hundred years will have been completed, when the first cycle is ended, which depended upon the appearance of the Sun of the Prophet and of the Moon of the Vilayat, then the influence of that cycle is ended and a second cycle begins in which the intimate precepts and hidden meanings of the former cycle are explained." He himself then adds these words: "In other words, and in order to render clearer this amazing statement which truly needs no interpretation, Siyyid Kazim tells us that the first cycle which lasts twelve hundred years is solely for the education of the bodies and of the spirits which are dependent upon them. It is like a child in the womb of the mother. The second cycle is for the education of the pure spirits, the souls which have no relation to the world of matter. It is as though God wished to elevate the spirit by means of the performance of its duty in this world. Therefore, when the first cycle is completed, the glory of which is the name of Muhammad, comes the cycle of the education of the intimates. In this cycle the appearances obey the intimates, just as in the preceding cycle the heavenly name of the Prophet, which is Ahmad, is the place of the appearance, the Master: `But this name must necessarily be found to be of the fruit of the best soil and of the purest air.'" Nicolas further adds in a footnote the following words: "The name of Ahmad mentioned above would lead one to believe that it refers to Shaykh Ahmad, but one cannot say, however, in speaking of Lahca, that it is the best of lands, or of the purest air. We know, on the contrary, that all the Persian poets sing the praises of Shiraz and of its ideal climate. It is only necessary to see what Shaykh Ahmad himself said of his country."
