Whatever diversity may exist among religions, the motive of all has been one: to cultivate and prepare the human heart for divine love. Sometimes the Spirit of Guidance drew the attention of mankind to see and admire the beauty of God in the firmament, sometimes in the trees and rocks, making them sacred trees, holy mountains, and purifying streams. Sometimes it has guided men's attention to see the immanence of the Lord among the beasts and birds, calling them holy animals, sacred birds. When man realized that there is no one in creation higher than himself he gave up his worship of the lower creation, recognizing the divine light most manifest in man. Thus by degrees the world evolved to see God in man, especially in the holy man who is God-conscious.
