Universal principles such as Good Mind, Righteousness, Dominion, Devotion, Health, and Life, are derived from Wisdom, and are accessible to the eye of the mind and human spirit, called in Pahlavi as the Menog realm. It derives its existence, order, and meaning from the menog world. The real dualism in Zarthushti theology is not metaphysical but ethical, a dualism between good and evil. The realm of Wisdom is expressed in a personalized theological language. By paying reverence to the water, earth, and fire of the getig creation, the celebrant praises the Creator, for these aspects of the created world exemplify the principles and powers of the menog realm.
Exemplification is different from symbolization.
A symbol is something that stands between the observer and that which is being signified. To exemplify something is to be a sample of it. The priests strive to live righteous lives and as bearers of ritual power, they become representatives of Wisdom. The entire consecrated ritual area and all objects and events within it, become a model and exemplifies a larger reality. The Yasna ceremony is also linked to cosmic time.
