A constant "why" arises in the minds of the intelligent, and when this "why" is answered by life to man's satisfaction, he goes on further and further, penetrating through all different planes of life; but when this "why" does not get a satisfactory answer from life, then doubt, dismay, and dissatisfaction arise and result in confusion, bewilderment, and despair. Sometimes belief proves to be worse than disbelief. This is when a person, set in his belief, hinders his own progress, not allowing his mind to go further into the research of life, refusing guidance and advice from another, in order that he may preserve his own belief. Thus a belief, which is preserved as a virtue, becomes the greatest sin.
