Yet through it all there is a certain rather vague and elusive unity of idea, a spirit, one might say, that in various forms penetrates and transmutes the varying material of creed and caste, of blood and race with which it is presented. In essence this is the spirit which regards the whole world as an unreal dream, an illusory changing scene of transformations, stretched over the realities of a higher ultimate world of Divine unity. Laws and customs are based not on a reasoned pursuit of the good as existent in this life; but upon the means, magical or supernatural, of acquiring merit in a supposed ultimate universe of timeless and permanent reality reached after final severance from the circle of birth and death. It is a spirit diametrically opposed to that Greek thought which placed before man as his final and only aim happiness or the excellent performance of function in the world we know. Hardly less is it opposed to the Semitic creeds which project the purposes and rewards of virtue into a similar world of similar perceptions and individualities conceived as existent on a higher plane attainable after death. For the unifying spirit of Hinduism, so far as it can be grasped as in any way _one_, rejects the world altogether as a reality and places its virtues not in any reasoned balance of human rights and duties, but in the observance of rituals and austerities commended by the authority of a hierarchy. Hence marriage also, as far as it approaches the ideal, is based upon considerations that are non-rational and belong rather to a mystical or supernatural way of regarding life. Marriage to the Hindu thinker and idealist has nothing to do, in its ultimate causes, with the preferences of one man or one woman, nothing to do with the pursuit of happiness in a palpitating finite and human life. He sees in it no free union of two human wills, joined for their own contentment in an isolated human relation. Rather it is the connection of two incarnations of the world spirit during an unreal moment of illusory existence. The proper husband and wife are recognized and selected by magical arts exercised under the authority of the Sacred Books by certain classes of the priesthood. They are joined under a right conjunction of the stars, interpreted by an hereditary expert in the magic art of astrology. Their marriage is sanctified by miraculous rites and blessed and transformed by the repetition of mysterious Sanskrit phrases. They enter their new state purified as by a consecration. In a word, they deal with a sacrament, not with a human contract. It is not the satisfaction of human feelings that is sought, but the fulfilment of a ritual duty to the family, in its relation to the Divine Spirit.
