Of all the Gods of the Rigveda Agni bears the closest relationship to the Perso-Jewish Messiah, and it is he also who stands closest to man's soul. He is rightly called king of the universe, as God of Gods, who created the world and called into life all beings that are upon it. He is the lord of the heavenly hosts, the guardian of the cosmic order and judge of the world, who is present as an invisible witness of all human acts, who as a "knower of nature" works in every living thing, and as a party to all earthly secrets illuminates the unknown. Sent down by his father, the Sky-God or Sun-God, he appears as the "light of the world." He releases this world from the Powers of Darkness and returns to his father with the "Banner of Smoke" in his hand as a token of victory. Agni blazes forth in the lightning flash from out of the watercloud, the "sea of the sky," in order to annihilate the Dæmons of Darkness and to release oppressed humanity from the fear of its tormentors. Thus, according to Isaiah xi., 4, the Messiah too will burn his enemies with the fiery breath of his mouth; and in this he is clearly a Fire-God. Again, in the Apocalypse of Esdras (chap. xiii.) the Seer beholds the "Son of Man" (Purusha) rise up from out of the sea, fly upon the clouds of heaven, destroy the hostile forces by the stream of fire which proceeded from his mouth, free the scattered Israelites from their captivity and lead them back into their country. [175] But this "first-born" son of the Sun-God and the Sky-God is at the same time the father and ancestor of men, the first man (Purusha), the head of the community of mankind, the guardian of the house and of the domestic flock, who keeps from the threshold the evil spirits and the enemies who lurk in the darkness. Agni enters the dwellings of men as guest, friend (Mitra), companion, brother and consoler of those who honour him. He is the messenger between this world and the beyond, communicating the wishes of men to the Gods above, and announcing to men the will of the Gods. He is a mediator between God and men who makes a report to the Gods of everything of which he becomes aware among mankind. Although indeed he takes revenge for the men's faults yet he is a gracious God, disposed to forgive, in his capacity of an expiatory, propitiatory and redeeming power, atoning for their sins and bringing them the divine grace. Finally, he is also the guide of souls--he conducts the Gods down to the sacrifices offered by man and makes ready for men the path upon which he leads them up to God. And when their time has come he, as the purifying fire, consumes their bodies and carries that which is immortal to heaven. [176]
