To most of us it sounds like a truism to-day when we are told that the moral goodness of a deed comes from the goodness of intention. But it is a truth which once came to a man like a revelation of light in the darkness and has not yet reached all the obscure corners of humanity. There are men we still see around us who fearfully follow, hoping thereby to gain merit, the path of blind formalisms, which have no living moral source in the mind. This will make us understand the greatness of Zarathushtra. The outer expression of truth reaches its white light of simplicity through its inner realization.
True simplicity is the physiognomy of perfection.
In the primitive stage of spiritual growth, when man is dimly aware of the mystery of the infinite in his life and the world, when he does not fully know the inward character of his relationship with this truth, his first feeling is either that of dread or of a greed of gain. This drives him into wild exaggeration in worship, into frenzied convulsion of ceremonialism. But in Zarathushtra's teachings, which are best reflected in his Gathas, we have hardly any mention of the ritualism of worship. Conduct and its moral motives, such as Vohumano. Asha and Aramaiti, have received almost the sole attention in them.
