=The Avesta= (_sacred text_) contains the only existing monuments of a once extensive literature. It is divided into distinct parts, made up of separate pieces and fragments, which, repeated orally from generation to generation, were probably collected and reduced to writing in their present form many centuries after the period of Zoroaster. The compositions in question are chiefly professed revelations and instructions to mankind, confessions, prayers to the Supreme Being and various inferior deities, and metrical hymns (_Gâthâs_), simple and some of them so grand as to be deemed the productions of Zoroaster himself. Zoroaster is represented in the Avesta as conversing with Ormazd, who, in answer to the inquiries of the sage, reveals his will, and prescribes the moral and ceremonial law. Thus, in the following passage, Zoroaster questions Ormazd:— “O Ormazd (Ahura Mazda), most holy spirit, creator of existent worlds, righteous One! What, O Ormazd, was the Word (more correctly, Ahuna Vairya, the name of a sacred verse) which you pronounced for me before the heaven, before the water, before the cow, before the tree, before the fire, before the righteous man, before the demons and noxious creatures?” Then Ormazd replies: “I will tell thee, most holy Zoroaster, what was the Creative Word I pronounced for thee before the heaven, before the water, before the cow, before the tree, before the fire, before the righteous man, before the demons and noxious creatures, before all the universe. Such is the whole of the Creative Word, which, even when unpronounced and unrecited, outweighs a thousand breathed prayers, which are not pronounced, nor recited, nor sung. And he who in this world, O most holy Zoroaster, remembers the whole of the Creative Word, or utters it, or sings it, I will lead his soul thrice across the bridge of the better world, to the better existence, to the better truth, to the better days. I pronounced this Speech which contains the Word and its working, before the creation of this heaven, and before the creation of the earth. “He is a holy man,” says Ormazd elsewhere, “who constructs upon the earth a habitation in which he maintains fire, cattle, his wife, his children, and flocks and herds. He who makes the earth produce grain, who cultivates the fruits of the fields, he maintains purity; he promotes the law of Ormazd as much as if he offered a hundred sacrifices.”
