with them "was the chariot which leads to heaven." Thus a second spirit was placed beside Agni, the bearer of gifts, and this spirit carried prayer into heaven, and was the means by which the priests influenced the gods, the power which compelled the gods to listen to them. This spirit is the personification of the cultus, the power of meditation. It lives in the acts of worship, in the prayers; it is the spirit which in these prayers is the constraining power upon the gods. In the faith of the Indians the gods grow by invocations and prayers; this spirit, therefore, gives them vigour and strength, and as he is able to compel the gods, he must himself be a mighty god. This spirit of prayer is a creation of the priestly families, a reflected expression of that power and compulsion which from all antiquity the Indians believed could be exercised upon spirits, and which they attribute to the power of meditation. The name of this deity no less than his abstract nature is a proof of his later origin. He is called Brahmanaspati, _i.e._ lord of prayer. "Brahmanaspati," we are told in the Vedas, "pronounces the potent form of prayer, where Indra, Varuna, Mitra, and the gods have made their dwellings."[159] The lord of prayer, the leader of songs, the creator of the songs by which the gods grow, and who gives them power, the "bright, gold-coloured," has in reality done the deeds of Indra. "He has cleft the clouds with his lightning, opened the rich hollow of the mountains (the hidden streams), driven the cows from the mountains, poured forth streams of water, chased away the darkness with his rays, has brought into being the dawn, the clear sky, and fire."[160] Thus did the priests transfer the achievements of the old god of storm and battle to their new god, their own especial protector, whom they now make the possessor of all divine attributes, and the father of gods. As this spirit was concealed, and lived in the acts of sacrifice, in the priests who offered it, in their prayers and meditations, and, on the other hand, had a power over the gods, guiding them and compelling them, Brahmanaspati, the spirit of the cultus, the mysterious force, the magic power of the rite, became with the priests the Holy, an impersonal essence, which at last was looked on by the priests as "Brahman."[161] It was not with the lightning, but with the Brahman, _i.e._ with the power of the Holy, that Indra burst asunder the cave of Vritra.[162]
