Man in all ages has tried to imagine and has passed his imagination on to his fellow men, saying, "God is such and such." He saw in the fire the purifying influence, he worshipped it and believed in it, and said to man, "I see God in this." He looked at the sun as something standing before the world without protection and giving light, and he said, "I will worship it." Man imagined God in nature, he gave sacredness to trees and to some birds and animals and called them sacred, and worshipped God in them.
