To those who followed him in the path of spiritual attainment, he showed the different aspects of nature and asked them what they could see behind it. He pointed out to his followers that the form, line, color, and movement that they saw before them and which attracted them so much must have been accomplished by an expert artist. It could all work mechanically and be perfect, but no mechanism, however perfect, can run without the help of an individual. Therefore he showed them that God is not an object which the imagination has made, though He is molded by man's imagination outwardly. In reality, God is the Being, such a perfect being, that, if compared with other living beings of this world, He is beyond comparison. He is the only Being. The way of worship taught by Zarathushtra was to worship God by offering homage to nature. For nature suggests to the soul the endless and unlimited Being hidden behind it all.
