The hymns of the @Rg-Veda are neither the productions of a single hand nor do they probably belong to any single age. They were composed probably at different periods by different sages, and it is not improbable that some of them were composed before the Aryan people entered the plains of India. They were handed down from mouth to mouth and gradually swelled through the new additions that were made by the poets of succeeding generations. It was when the collection had increased to a very considerable extent that it was probably arranged in the present form, or in some other previous forms to which the present arrangement owes its origin. They therefore reflect the civilization of the Aryan people at different periods of antiquity before and after they had come to India. This unique monument of a long vanished age is of great aesthetic value, and contains much that is genuine poetry. It enables us to get an estimate of the primitive society which produced it--the oldest book of the Aryan race. The principal means of sustenance were cattle-keeping and the cultivation of the soil with plough and harrow, mattock and hoe, and watering the ground when necessary with artificial canals.
"The chief food consists," as Kaegi says, "together with bread, of various preparations of milk, cakes of flour and butter, many sorts of vegetables and fruits; meat cooked on the spits or in pots, is little used, and was probably eaten only at the great feasts and family gatherings. Drinking plays throughout a much more important part than eating [Footnote ref 7]." The wood-worker built war-chariots and wagons, as also more delicate carved works and artistic cups. Metal-workers, smiths and potters continued their trade. The women understood the plaiting of mats, weaving and sewing; they manufactured the wool of the sheep into clothing for men and covering for animals. The group of individuals forming a tribe was the highest political unit; each of the different families forming a tribe was under the sway of the father or the head of the family. Kingship was probably hereditary and in some cases electoral. Kingship was nowhere absolute, but limited by the will of the people. Most developed ideas of justice, right and law, were present in the country. Thus Kaegi says, "the hymns strongly prove how deeply the prominent minds in the people were persuaded that the eternal ordinances of the rulers of the world were as inviolable in mental and moral matters as in the realm of nature, and that every wrong act, even the unconscious, was punished and the sin expiated."[Footnote ref 8] Thus it is only right and proper to think that the Aryans had attained a pretty high degreeof civilization, but nowhere was the sincere spirit of the Aryans more manifested than in religion, which was the most essential and dominant feature of almost all the hymns, except a few secular ones. Thus Kaegi says, "The whole significance of the Rigveda in reference to the general history of religion, as has repeatedly been pointed out in modern times, rests upon this, that it presents to us the development of religious conceptions from the earliest beginnings to the deepest apprehension of the godhead and its relation to man [Footnote ref 9]."
