But Brahmanism became corrupted. Like the Mosaic Law, under the sedulous care of the sacerdotal orders it ripened into a most burdensome ritualism. The Brahmanical caste became tyrannical, exacting, and oppressive. With the supposed sacredness of his person, and with the laws made in his favor, the Brahman became intolerable to the people, who were ground down by sacrifices, expiatory offerings, and wearisome and minute ceremonies of worship. Caste destroyed all ideas of human brotherhood; it robbed the soul of its affections and its aspirations. Like the Pharisees in the time of Jesus, the Brahmans became oppressors of the people. As in Pagan Egypt and in Christian mediaeval Europe, the priests held the keys of heaven and hell; their power was more than Druidical. But the Brahman, when true to the laws of Menu, led in one sense a lofty life. Nor can we despise a religion which recognized the value and immortality of the soul, a state of future rewards and punishments, though its worship was encumbered by rites, ceremonies, and sacrifices. It was spiritual in its essential peculiarities, having reference to another world rather than to this, which is more than we can say of the religion of the Greeks; it was not worldly in its ends, seeking to save the soul rather than to pamper the body; it had aspirations after a higher life; it was profoundly reverential, recognizing a supreme intelligence and power, indefinitely indeed, but sincerely,--not an incarnated deity like the Zeus of the Greeks, but an infinite Spirit, pervading the universe. The pantheism of the Brahmans was better than the godless materialism of the Chinese. It aspired to rise to a knowledge of God as the supremest wisdom and grandest attainment of mortal man. It made too much of sacrifices; but sacrifices were common to all the ancient religions except the Persian. "He who through knowledge or religious acts Henceforth attains to immortality, Shall first present his body, Death, to thee." Whether human sacrifices were offered in India when the Vedas were composed we do not know, but it is believed to be probable. The oldest form of sacrifice was the offering of food to the deity. Dr. H. C. Trumbull, in his work on "The Blood Covenant," thinks that the origin of animal sacrifices was like that of circumcision,--a pouring out of blood (the universal, ancient symbol of _life_) as a sign of devotion to the deity; and the substitution of animals was a natural and necessary mode of making this act of consecration a frequent and continuing one. This presents a nobler view of the whole sacrificial system than the common one. Yet doubtless the latter soon prevailed; for following upon the devoted life-offerings to the Divine Friend, came propitiatory rites to appease divine anger or gain divine favor. Then came in the natural human self-seeking of the sacerdotal class, for the multiplication of sacrifices tended to exalt the priesthood, and thus to perpetuate caste.
