Indian thought, as has been already indicated, worked out a complete identification of life with the moral order by means of the doctrine of the Deed (p. 217). The scheme of transmigration took up the earlier ideas of the elder thinkers. The Vedic poets had told of the land of Yama, who was sometimes presented as the first man to die and enter the heavenly world. In one hymn he is associated with Varuna in the highest heaven, where the pious live from age to age, and are sometimes identified with the sun's rays or the stars. There kindred were gathered, and warriors and poets received their reward, and the devout realised the object of their prayers; and Yama sat under a tree of goodly leaves, drinking with the gods the life-giving soma-juice, father and master of the house, tending the heavenly sires. Deep below was the dark pit for those who would not sacrifice to Indra, or persecuted his worshippers. There were fiends of various kinds to torment the wicked, the untruthful, or the seducer. But there are no traces of any specific judgment, with definite awards of heaven and hell. In the later scheme of life founded on the conception of Karma such a tribunal might seem unnecessary: the product of the past works {244} out its own result. But as Buddhist folklore shows, popular theology required the pronouncement of a judge, and Yama took his place as Lord of hell and King of Righteousness. By what channels the doctrine of successive world-ages entered Hindu religion cannot be definitely determined. Early Buddhist teaching assumes it as familiar, though it is not included in the prior Brahmanical literature; and minutely describes the great conflagration which will consume the universe through the heat engendered by the appearance of seven suns. Karma, however, could not be destroyed. No fire could burn it, nor could the other agencies of dissolution, like water or wind, drown or disperse it. It must proceed unerringly to its results. These might be for a time suspended, they could not be frustrated for ever. Their energies lay latent, waiting their opportunity. So a new world would arise to provide the means and the field for their operation, and from age to age, through seasons of dissolution and restoration, with intervals of incalculable time, the endless process would fulfil its round. This would be no literal repetition. The history of a new world-age would be quite fresh, for the potencies of Karma were of infinite variety, and were for ever being re-shaped, cancelled, or extended by the action of the new personalities--divine, human, demonic--(reincarnation might also take place in animal or plant)--in {245} which they were embodied. But the immense series led to nothing. Buddhist imagination filled the universe with worlds, each with its own systems of heaven and hell, and projected æons upon æons into immeasurable time, but the sequence pointed to no goal, for what could arrest the inexorable succession?
