The _naïve_ conception that the god drank vigour and courage out of the sacrificial bowl is developed among the Aryas in a very peculiar manner. From this fact they derived the idea that the sacrifice gave power to the gods generally to increase their strength; that the gods "grew" by prayer and sacrifice. Thus we read: "The suppliants, extolling Indra by their songs of praise, have strengthened him, to slay Ahi. Increase, O hero Indra, in thy body, praised with piety, and impelled by our prayers. The hymns whet thy great strength, thy courage, thy power, thy glorious thunder-club."[108] As it is men who offer sacrifice to the gods, this conception gives mankind a certain power over the deities; it lies with them to strengthen the gods by sacrifice and gifts; they can compel the gods to be helpful to them, if only they understand how to invoke them rightly. The holy words, _i.e._ the invocations, are, in the conception of the Veda, "a voyage which leads to heaven." Hence those who are acquainted with the correct mode of prayer and offering become magicians, who are in a position to exercise force over the gods. The idea that man has power to compel the gods is very _naïve_, childlike, and childish; in its most elementary form it lies at the root of fetishism. In other nations also great weight is laid on the correct mode of offering sacrifices, as the essential condition of winning the grace of the gods; but the conception that a hearing must attend a sacrifice and prayer correctly made is far more strongly present in the Indians, than in any other civilised people. Yet the hymns of the Veda are far above fetishism, which attempts to exercise direct external compulsion upon the gods. The Indian faith is rather that this effect is obtained not merely by the custom of sacrifice, but by the intensity of invocation, by the power of meditation, by elevation of spirit, by the passionate force of prayer, which will not leave the god till he has given his blessing. It is inward, not outward compulsion that they would exercise. Developed in a peculiar direction, this mode of conception is of deep and decisive importance for the religious and civic views of the Indians.
