In this manner, man passed from the stage of contending against the spirits to one of placating them. It was believed that certain men carried more favor with the spirits than others, and these became the original priests, called the "Shamans." Another expedient for warding off evil spirits was by means of the fetish. The primitive fetish was an object containing an active friendly spirit, which, if worn by the individual, protected him from the evil spirits. In a short while the manufacture of fetishes became a sacred profession, and the men who were thought to fashion the best ones became the professional holy men of the period, the priests. At first, idols were used to drive away the evil spirits, and then, the conception changed to one of attracting the good spirits to man. From the individual fetish man passed to tribal ones, which in their first form were huge boulders and trees. As the primitive mind gained cunning, it slyly smeared the surface of the idol with oily substances, hoping that the spirit, like some wild beast, would come and lick, be gratified, and remain in the idol. When some favorable signs denoted that a good spirit had entered into the idol, it was regularly smeared with oils and then blood, in the hope that the spirit would be pleased sufficiently to remain there permanently. As time went on, it became a custom, a rite, and the spirit having performed to the satisfaction of the tribe, ways were invented to manifest their gratitude. Instead of smearing the idol with blood, it was thought more fitting that an animal be killed and offered to the good spirit contained within the idol. In this manner arose the beginning of "sacrifice." It was at this time, when man began to persuade the idols or spirits to do things for his benefit that religion began. Slowly, slowly, down through the ages, as the mind of man progressed, his self-made religious conceptions advanced. He now worshiped idols, and these idols were his gods. The Celts, the Babylonians, the Greeks, the Romans, all had their idols. All were certain that their gods were the true ones, and that the others were all inferior and even false gods. But, is the modern worshipper who is contemptuous of the ancients very different from them? The centuries pass by, and in their wake is man's self-conceived religion. Now, some men take the prerogative in the manufacture of religion, and there evolve Brahmanism, Jainism, Buddhism, Hinduism, Confucianism, Taoism, and Zoroastrianism, all inspired, all supernatural, and with their myriads of followers who believed and still believe that theirs is the only true creed.
