When a man or a woman dedicates his or her life to spread the moral and spiritual truths of his or her religion in a spirit of selflessness and self sacrifice, then it becomes the noblest of all truth sharings. Modern sociologists and historians say with one voice today that human kind's very survival depends on moral and spiritual values. History shows that mighty civilizations in the past declined and passed away because they neglected the moral and spiritual aspects of the society and developed only the material aspect. Therefore, whether the spread of moral and spiritual values is undertaken by the laity or clergy, it is a good act and a noble act. Truth, however, is not the monopoly of one religion or one sect.
Truth is open to inquiry and investigation.
And truth must be universally applicable. Above all, truth must be spread truthfully, ethically and peacefully. All great religious teachers used the methods of preaching, teaching and healing. They never branded those who did not accept their teachings as heathens, idolaters, pagans, atheist and heretics and condemned them to hell-fire.
