There are some who have the urge to acquire knowledge and learn; who are in search of Truth. There are others who have acquired wealth and power and consider themselves successful to the point of feeling that there is nothing lacking in them which needs to be compensated for. When the call of Truth is given, it is mostly the former kind of people who accept it, unlike the latter who do not attach any significance to it. They never give it any serious thought, and therefore its importance does not become clear to them. The call of Truth provides answers for those who earnestly go in quest of the truth, and gives those who are not so inclined, a logical conclusion to their arguments. With regard to the former, the aim is to enable them to accept the truth; as for the others, it is meant to make them concede that at least the divine message had been conveyed to them in full.
