Zarathustra's spiritual attainment came by his communication with Nature first. He appreciated, adored, and worshiped the sublimity of Nature, and he saw wisdom hidden in the whole creation. He learned and recognized from that the being of the Creator, acknowledged His perfect wisdom, and then devoted his whole life to glorifying the Name of God. To those who followed him in the path of spiritual attainment, he showed the different aspects of Nature, and asked them to see what they could see behind it all. He pointed out to his followers that the form and line and color and movement that they saw before them, and which attracted them so much, must have been accomplished by an expert artist. It cannot all work mechanically and be perfect. The mechanism, however much perfected, cannot run without the help of an engineer. Therefore he showed to 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.
