Amid these terrible convulsions of the air and ground, these antagonisms of outward good and evil, Zoroaster developed his belief in the dualism of all things. To his mind, as to that of the Hebrew poet, God had placed all things against each other, two and two. No Pantheistic optimism, like that of India, could satisfy his thought. He could not say, "Whatever is, is right"; some things seemed fatally wrong. The world was a scene of war, not of peace and rest. Life to the good man was not sleep, but battle. If there was a good God over all, as he devoutly believed, there was also a spirit of evil, of awful power, to whom we were not to yield, but with whom we should do battle. In the far distance he saw the triumph of good; but that triumph could only come by fighting the good fight now. But his weapons were not carnal. "Pure thoughts" going out into "true words" and resulting in "right actions"; this was the whole duty of man. § 6. Character of the Zend Avesta. A few passages, taken from different parts of the Zend Avesta, will best illustrate these tendencies, and show how unlike it is, in its whole spirit, to its sister, the Vedic liturgy. Twin children of the old Aryan stock, they must have struggled together like Esau and Jacob, before they were born. In such cases we see how superficial is the philosophy which, beginning with synthesis instead of analysis, declares the unity of all religions before it has seen their differences. There _is_ indeed, what Cudworth has called "the symphony of all religions," but it cannot be demonstrated by the easy process of gathering a few similar texts from Confucius, the Vedas, and the Gospels, and then announcing that they all teach the same thing. We must first find the specific idea of each, and we may then be able to show how each of these may take its place in the harmonious working of universal religion. If, in taking up the Zend Avesta, we expect to find a system of theology or philosophy, we shall be disappointed. It is a liturgy,--a collection of hymns, prayers, invocations, thanksgivings. It contains prayers to a multitude of deities, among whom Ormazd is always counted supreme, and the rest only his servants.
