Not only do we obtain from the Gâthâs a glimpse of Zarathustra attended by zealous disciples, eager to proclaim the good tidings he brought: we learn something also of the opposition he encountered from the adherents of the older faith. And since he actually names himself in the course of one of these compositions, which bears every appearance of genuineness and antiquity, we need not doubt the authenticity of the picture therein given of his relations to these opponents. They were the adherents of the old Devas, the gods whom Zarathustra dethroned;—polytheists, averse to this unheard-of introduction of monotheism into their midst. And they formed, at least during a part of the prophet's life-time possibly during the whole of it, by far the stronger party, for he refers to them in these terms:—
"To what country shall I go? where shall I take refuge? what country gives shelter to the master (Zarathustra) and his companion? None of the servants pay reverence to me, nor do the wicked rulers of the country. How shall I worship thee further, living Wise One?
"I know that I am helpless. Look at me being amongst few men, for I have few men (I have lost my followers or they have left me); I implore thee weeping, thou living God who grantest happiness as a friend gives a present to his friend. The good of the good mind is in thy own possession, thou True One!...
"The sway is given into the hands of the priests and prophets of idols, who, by their atrocious actions, endeavor to destroy the life of man....
"To him who makes this very life increase by means of truth to the utmost for me, who am Zarathustra myself, to such an one the first (earthly) and the other (spiritual) life will be granted as a reward together with all good things to be had on the imperishable earth. Thou, living Wise One, art the very owner of all these things to the greatest extent; thou, who art my friend, O Wise One!" (Yasna. xlv. 1, 2, 11, 19.)
And elsewhere we come across this exclamation: "What help did Zarathustra receive, when he proclaimed the truths? What did he obtain through the good mind?" (Ibid., xlix. 12.)
And the piteous question is put to Ahura Mazda: "Why has the truthful one so few adherents, while all the mighty, who are unbelievers, follow the Liar in great numbers?" (Ibid., xlvii. 4.)
These simple and natural verses point to a prophet who was—for a time at least—without honor in his own country. Whereas the later representations of his career depict him as the triumphant revealer of a new faith, before whose words of power the "Devas," or god of polytheism, flee in terror and dismay, we meet with him here in the character of a persecuted and lonely man, unsupported by the authorities of his nation, opposed by a powerful majority, and imploring, in the distress and desolation of his mind, the all-powerful assistance of his God. Such is the reality; how widely it differs from the fiction we have already seen. But as is always the case with great prophets, who are rejected in their own days and honored after their death, the reality is forgotten; the fiction is universally accepted.
Little need be said of the doctrines taught by Zarathustra. His main principle is belief in the one great God, Ahura Mazda, whom he substitutes for the many gods of the ancient Aryans. He was in fact the author of a monotheistic reformation. The worshipers of these deities are often referred to in opprobrious terms, more especially as "liars," or "adherents of lies," while the devotees of Ahura are spoken of as the good, or as those who are in possession of the truth. It is only through the spirit of lying that the godless seek to do harm; through the true and wise God they cannot do it (Yasna, xlvii. 4). This God, the friend of the prophet, is honored in language of deep and simple adoration; not with the mere vapid epithets of praise which become common in the later sections of the Zend-Avesta. Zarathustra feels himself entirely under his protection, and describes himself ready to preach whatever truths this great Spirit may instruct him to declare.
Beyond this great central dogma—which he announces with all the fervor of a discoverer—there is nothing of a very distinctive kind in his theology. The doctrine of a separate evil spirit opposed to Ahura Mazda does not hold in the Gâthâs that place which it afterwards obtained in the sacred literature of the Parsee. Dr. Haug considers that Zarathustra held merely a philosophical dualism, the two principles of existence—bad and good—being united in the supreme nature of the ultimate Deity. From this great and all-wise Being every good thing emanates. He is the inspirer of his prophet; the teacher of his people; the counselor in the many perplexing questions that harass the minds of his worshipers. To him the pious souls resort in trouble; by him both earthly possessions and spiritual life are granted to those who rightly seek him. Ahura Mazda is the true God; and there is no other God but Ahura Mazda.
