89. Before modern means of transport were invented and communication between different continents was still almost impossible, or at least very difficult, terrestrial people on these continents lived isolated from and independent of each other. And as the daily struggle for existence was not quite the same on each continent, the experiences of these people were also of a different nature; this necessarily resulted in their concepts of morality and idealism being different too, deviating from each other in different parts of the world. So each continent had its special forms of religion, idealism and morality. Gradually, as the light radiation increased, the most advanced religions took a direction towards "internationalism", and the followers of these religions believed that their special religion ought to grow and envelop all peoples of the world, while the other existing religions were considered "heathen" and their adherents "infidels". But, as it was only the inner core of these religions that was of universal or international nature, while the outer forms and adaptations were founded just for the specific people among whom each of the said religions had arisen, so a religion of this kind could never be quite satisfactory to any people other than those to whom it was directly adapted. And the various so-called "world religions" therefore appear sharply opposed to each other and not one of them would be in a position to fulfil the conditions absolutely necessary for a religion which should be a special religion for the entire world and for terrestrial mankind as a whole; but as they do possess international ideas and tendencies within themselves, as mentioned above, each of them influences terrestrial humanity towards aiming at unity, towards "one flock, one shepherd". And each of the religions, communities and religious societies within the whole of terrestrial humanity is, in fact, comparable with the scattered, single parts of a nebula, condensing and eventually coming to constitute a solid body. This solid body is the absolute union of all terrestrial people under one religion.
