That it was the _blood_, which was the chief element in the covenanting-sacrifice, is evident from all the facts in the case. Thus, in the Aitareya-brāhmana, it is said: “The gods killed a man for their victim [of sacrifice]. But from him thus killed, the part which was fit for a sacrifice went out and entered a horse. Thence, the horse became an animal fit for being sacrificed. The gods then killed the horse, but the part of it fit for being sacrificed went out of it and entered an ox. The gods then killed the ox, but the part of it fit for being sacrificed went out of it and entered a sheep. Thence it entered a goat. The sacrificial part remained for the longest time in the goat; thence it [the goat] became preeminently fit for being sacrificed!” Indian history shows that this has been the progress of reform, from the days of human sacrifice downward. “It is remarkable that in Vedic times, even a cow ... was sometimes killed; and goats, as is well known, are still sacrificed to the goddess Kālī.”[319] Kalī, also called Doorgā, is the blood-craving goddess. The blood of one human victim, it is said, “gives her a gleam of pleasure that endures a thousand years; and the sacrifice of three men together, would prolong her ecstacy for a thousand centuries.”[320] Bishop Heber indicates the “sacrificial part” of the goat as he saw it offered at a temple of Kālī in Umeer. He was being shown by his guide through that city, on his first visit there, and the guide proposed a look at the temple. “He turned short, and led us some little distance up the citadel, then through a dark, low arch into a small court, where, to my surprise, the first object which met my eyes was a pool of blood on the pavement, by which a naked man stood with a bloody sword in his hand.... The guide ... cautioned me against treading in the blood, and told me that a goat was sacrificed here every morning. In fact a second glance showed me the headless body of the poor animal lying before the steps of a small shrine, apparently of Kali. The Brahman was officiating and tinkling his bell.... The guide told us, on our way back, that the tradition was, that, in ancient times a man was sacrificed here every day; that the custom had been laid aside till Jye Singh [the builder of Umeer] had a frightful dream, in which the destroying power appeared to him, and asked why her image was suffered to be dry [It is _blood_, not _flesh_, that moistens]. The Rajah, afraid to disobey, and reluctant to fulfil the requisition to its ancient extent of horror, took counsel and substituted a goat [in which as well as in man there is blood--which is life--which is the chief thing in a sacrifice Godward] for the human victim; with which the ‘Dark goddess of the azure flood, Whose robes are wet with infant tears, Skull-chaplet wearer, whom the blood Of man delights three thousand years,’ was graciously pleased to be contented.”[321]
