Substance—From the Latin substare, be under, be firm, support. Substance (vastu in Sanskrit) is the underlying support of all phenomena. It is the eternal Brahman, the cause, of which the world is the effect. The Vedic view of the substance of the world is different from the Christian view, called creatio ex nihilo. According to this theory put forward by Augustine (175-242), God created the world out of nothing. Augustine's reasoning was based on the Biblical statement that in the beginning there was only God. Creatio ex nihilo was an attempt to break out of the paradoxical question, If in the beginning there was only God, and God is eternal, why is the world ever-changing? It was assumed that a doctrine of the material world's direct emanation from God's own substance could be true only if the material world had the same nature as God. But since it does not, and since God was alone in the beginning, He must have created the world from nothing. There is a paradox upon which creatio ex nihilo stumbles: ex nihilo, nihil fit, From nothing, nothing comes. According to the Vedic view, the substance of creation is tattva, true, just as God is true. The tattva of matter (prakṛti) is eternal, but it assumes temporary forms as God wills. Like a shadow, the material creation resembles the original form of the substance. But it does not have the potency of the original. Yet it has no other source than the substance. Its source is not nothing. See Absolute, Brahman.
