Among human beings some are clean and pure, while some are unclean. Some souls draw nourishment from the things that are liked by God, while others have a taste for things that are the favourites of their base selves or of Satan.Under normal conditions, both types of people live together. On the face of it, there appears to be no difference between them. So, Almighty God causes a struggle between True and false, so that the people of both types separate from each other and it becomes clear as to who is who. During this struggle it becomes clear as to who immediately accepts the Truth when it comes before him and who rejects it; who, in dealing with others remains within the limit of justice, and who resorts to injustice; who remains modest and humble in the world and who becomes arrogant, who spends money for the cause of Truth and who spends as a matter of prejudice and show.The actions of those who expend their efforts in ways other than the way of Truth are glorified and made handsome in their eyes by Satan in such a way that they start thinking that they are performing superior acts; that they are proceeding towards a glorious future. But this misunderstanding is short-lived. Very soon man reaches the stage when he comes to know that whatever he had done was merely a wastage of his energy and money. The future towards which he was proceeding was only one of unfulfilled longing and frustration, though on the basis of false hopes he had considered it a journey towards a bright future. When the call for pure religion is given, all those people who had gained a position of leadership on the basis of adulterated religion feel adversely affected by that call. So, they spend all their energy in protecting the custom-based, traditional structure which had conferred the position of superiority on them. But such people necessarily fail when opposed by the unadulterated Truth, sometimes in the field of argument and sometimes in the field of action as well.The activities of this world have been designed just to separate pure and impure souls from each other. When this process of sorting out is over, God will send the pure souls to paradise and assemble the impure souls and thrust them into hell.
