404 Speculations in the Medical Schools [ch. determine the actual nature of their good or bad effects, success or failure. This implies a disbelief in our power of directly controlling our fortunes by our efforts. The theory of karma thus involves a belief in the mysterious existence and ripening of the sinful and virtuous elements of our actions, which alone in their course of maturity produce effects. If the theory that sins bring their punishment, and virtues produce their beneficial effects, of themselves, is accepted, its logical consequences would lead us to deny the possibility of mere physical actions modifying the fruition of these karmas. So the acceptance of the moral properties of actions leads to the denial of their direct physical consequences. If through my honest efforts I succeed in attaining a happy state, it is contended that my success is not due to my present efforts, but it was predestined, as a consequence of the good deeds of my previous birth, that I should be happy. For, if the fruition was due to my ordinary efforts, then the theory that all happy or unhappy experiences are due to the ripening of the karmas of the previous births falls to the ground. If, on the other hand, all success or failure is due to our proper or improper efforts, then the capacity of sins or
misery or happiness may naturally be doubted. and the cases where even our best efforts are attended with failure are not explained. But, if our ordinary efforts cannot effect anything, and if the modes of our experiences, pleasures and sufferings, and the terın of our life are already predestined, then none of our efforts are of any use in warding off the calamities of this life, and the purpose of the science of medicine is baffled. In common-sense ways of belief one refers to "fate" or "destiny" only when the best efforts fail, and one thinks that, unless there is an absolute fatality, properly directed efforts are bound to succeed. Caraka's theory seems to embody such a common-sense view. But the question arises how, if this is so, can the immutability of the law of karma be preserved? Caraka thinks that it is only the extremely good or bad deeds that have this immutable character. All other effects of ordinary actions can be modified or combated by our efforts. Virtue and vice are not vague and mysterious principles in Caraka, and the separation that appears elsewhere between the moral and the physical sides of an action is not found in his teaching? He seems to regard the "good," or the all-round manifold
