The Mobed _Azar Khirad_ relates in his book that the _Zand_ contains twenty-one _Nosks_, or “parts,” every _Nosk_ having a particular name in Zand and Parsi according to the following list:[429] _Yathá_, _Ita_, _Ahu_, _Wíría_, _Alartúsh_, _Nadar_, which they call in Arabic _Búfastál_, and in Parsi _Favaímasíhan_. This Nosk treats of the stars, constellations, order of the heavens, the aspects, the good and evil influences of the heavenly bodies, and such like topics. The other Nosks are: the _Ashád_, _Chíd_, _Hashú_, _Wankawísh_, _Wazda_, _Mankahú_, _Sítanú_, _Nan_, _Ankahísh_, _Marzái_, _Khashar_, _Machá_, _Ahrá_, _Ayám_, _Darkúbíú_ and _Astarám_: all the sciences are contained in the Zand, but some are mentioned enigmatically and by way of allusion. At present there are fourteen complete Nosks possessed by the Dostúrs of Karman, the other seven being incomplete, as through the wars and dissensions which prevailed in Iran some of the Nosks have disappeared, so that, notwithstanding the greatest researches, the Nosks have come into their hands in a defective state. Zaratusht Báhrám, the son of _Pazhdú_, relates that, at the time of the promulgation of the pure faith in Iran, there lived in India a sage of profound learning, named _Jangrangháchah_,[430] whose pupil _Jamasp_[431] had been during many years, a circumstance which procured him great distinction. On being informed of Gushtasp’s conversion, he wrote an epistle to the great king, to dissuade him from the profession of the pure faith. By the king’s command, this sage came to Iran to hold a disputation with Zardusht, who said to him: “Listen to one Nosk of this Asta which I have received from God, and attend to its interpretation.” Upon this, at the illustrious prophet’s command, one of his disciples read a Nosk in which God said thus to Zardusht: “On the promulgation of the pure faith, there shall come from Hindustan a wise man, named _Jangrangháchah_, who will ask thee questions, after such and such guise, the answers to which are after this manner, thus answering all his questions: “By this same Nosk his condition was improved, And the answer to each question was correctly given.”
