"The way of worship taught by Zarathustra is to worship God by offering homage to the nature. For nature suggests to the soul the endless and unlimited Being hidden behind it all.
They keep a constandly burning fire in their place of worship, but they keep it before them when thinking of God, for fire purifies all things and the light within purifies all souls".
