There arises a question in the heart of the inquirers, "Then what is this variety of religions which has engaged humanity for years in conflict with one another, so that most of the wars and battles were fought in the cause of religion?" This only shows the childish character of human nature. Religion which was given and is given, wherever it is given, religion which was given for unity, for harmony, for brotherhood, was used by childish human nature to fight and to dispute and to engage themselves in battles for years and years. And the most amusing thing for a thoughtful person is to think and see how this has given in the past history a most sacred character to war, to battle, and called it sacred war, or holy war.
