It must not however be supposed that Hindus like the prospect of transmigration. On the contrary from the time of the Upanishads and the Buddha to the present day their religious ideal corresponding to salvation is emancipation and deliverance, deliverance from rebirth and from the bondage of desire which brings about rebirth. Now all Indian theories as to the nature of transmigration are in some way connected with the idea of _Karma_, that is the power of deeds done in past existences to condition or even to create future existences. Every deed done, whether good or bad, affects the character of the doer for a long while, so that to use a metaphor, the soul awaiting rebirth has a special shape, which is of its own making, and it can find re-embodiment only in a form into which that shape can squeeze. These views of rebirth and karma have a moral value, for they teach that what a man gets depends on what he is or makes himself to be, and they avoid the difficulty of supposing that a benevolent creator can have given his creatures only one life with such strange and unmerited disproportion in their lots. Ordinary folk in the East hope that a life of virtue will secure them another life as happy beings on earth or perhaps in some heaven which, though not eternal, will still be long. But for many the higher ideal is renunciation of the world and a life of contemplative asceticism which will accumulate no karma so that after death the soul will pass not to another birth but to some higher and more mysterious state which is beyond birth and death. It is the prevalence of views like this which has given both Hinduism and Buddhism the reputation of being pessimistic and unpractical. It is generally assumed that these are bad epithets, but are they not applicable to Christian teaching? Modern and medieval Christianity—as witness many popular hymns—regards this world as vain and transitory, a vale of tears and tribulation, a troubled sea through whose waves we must pass before we reach our rest. And choirs sing, though without much conviction, that it is weary waiting here. This language seems justified by the Gospels and Epistles. It is true that some utterances of Christ suggest that happiness is to be found in a simple and natural life of friendliness and love, but on the whole both he and St Paul teach that the world is evil or at least spoiled and distorted: to become a happy world it must be somehow remade and transfigured by the second coming of Christ. The desires and ambitions which are the motive power of modern Europe are, if not wrong, at least vain and do not even seek for true peace and happiness. Like Indian teachers, the early Christians tried to create a right temper rather than to change social institutions. They bade masters and slaves treat one another with kindness and respect, but they did not attempt to abolish slavery.
