Param Pujya Dadashri(master of spiritual science), through his Gnan (knowledge of the self-realization), has exposed the science of karma, exactly as it is. It is due to ignorance that, while experiencing the karmas, raag-dwesh (likes-dislikes) is created, which in turn creates new seeds of karma that mature in the next life and have to be suffered. Gnanis prevent one from creating new seeds of karmas. When all karmas have been completely exhausted one attains the final Moksha.
