Few references to death and the future life are to be found in the hymns of the Rigveda, as the optimistic and active Vedic Indian, unlike his descendants in later centuries, seems to have given little thought to the other world. Most of the information to be gained about their views of the next life are to be found in the funeral hymns of the last book. The belief here expressed is that fire or the grave destroys the body only, while the real personality of the deceased is imperishable. The soul is thought to be separable from the body, not only after death, but even during unconsciousness (x. 58). There is no indication here, or even in the later Vedas, of the doctrine of the transmigration of souls, though it was already firmly established in the sixth century B.C. when Buddhism arose. One passage of the Rigveda, however, in which the soul is spoken of as departing to the waters or the plants, may contain the germs of the theory. CHAPTER V PHILOSOPHY OF THE RIGVEDA According to the Vedic view, the spirit of the deceased proceeded to the realm of eternal light on the path trodden by the fathers, whom he finds in the highest heaven revelling with Yama, king of the dead, and feasting with the gods. In one of the funeral hymns (x. 14, 7) the dead man is thus addressed:-- Go forth, go forth along those ancient pathways To where our early ancestors departed. There thou shalt see rejoicing in libations The two kings, Varuna the god and Yama. Here a tree spreads its branches, in the shade of which Yama drinks soma with the gods, and the sound of the flute and of songs is heard. The life in heaven is free from imperfections or bodily frailties, and is altogether delectable. It is a glorified life of material joys as conceived by the imagination, not of warriors, but of priests. Heaven is gained as a reward by heroes who risk their lives in battle, but above all by those who bestow liberal sacrificial gifts on priests. Though the Atharva-veda undoubtedly shows a belief in a place of future punishment, the utmost that can be inferred with regard to the Rigveda from the scanty evidence we possess, is the notion that unbelievers were consigned to an underground darkness after death. So little, indeed, do the Rishis say on this subject, and so vague is the little they do say, that Roth held the total annihilation of the wicked by death to be their belief. The early Indian notions about future punishment gradually developed, till, in the post-Vedic period, a complicated system of hells had been elaborated. Some passages of the Rigveda distinguish the path of the fathers or dead ancestors from the path of the gods, doubtless because cremation appeared as a different process from sacrifice. In the Brahmanas the fathers and the gods are thought to dwell in distinct abodes, for the "heavenly world" is contrasted with the "world of the fathers."
