Holy Dialogue (Pravachana Vakhyalu):
March 17, 2014: God must have modified Himself into this universe, as milk modifies itself into yogurt or curd. Otherwise, we cannot explain how God creates this world. The assumption of a totally independent material existence outside God is not permissible for various reasons, one of the reasons being that it would limit God to a finite entity. Finitude is that state of being which has something outside it, another finite. Everyone is limited and everyone is finite because of the existence of other finitudes - in the sense that there are things and persons outside every person and thing. God also would become finite because the existence of another thing outside God, such as the material for creation, would condition God to a limited existence. Therefore, the doctrine that the creation of the world came out of an already-existing material would be a contending factor before God, an opposition to God. God would then not be infinite. Therefore, God must Himself have become this universe.
