It means that however much we may think our path is the best for us that we must allow other people a similar dedication to their own path, even if it is contrary to ours, including the freedom not to follow any path at all. Pluralism means that we must make the freedom of religious practice a more important principle than the supremacy of any particular belief. We should not only respect but uphold our neighbor's right to follow another religion, even if we think that it is contrary to the real truth. This means that missionary efforts to convert others by persuasion and intimidation should come to an end and be replaced by a free examination of religious issues with honesty, courtesy and friendliness. To arrive at truth in any field we need freedom.
Freedom creates diversity.
Both freedom and diversity allow for creative growth and inquiry. In this development truth can be arrived at as an individual experience, rather than imposed upon the resistant individual as a collective belief which makes it little more than a blind emotion. Human beings naturally have their different temperaments, inclinations and states of development. We should have learned after so much bloodshed throughout history that to try to impose one way of thought on all people is an error. It is not only not spiritual, it goes against nature and life which are filled with every sort of variation.
