Everything that nurtures prejudice, whether that prejudice be religious, sectarian, patriotic or political, is a destroyer of the firm foundation of humanity. Prejudice is the destroyer of human happiness, no matter what form it assumes. Until existing prejudices pass away it is impossible for the world of humanity to advance. Everywhere we witness religious, racial, sectarian, patriotic or political bias or partisanship.

For six thousand years the world of humanity has been restless and the cause of its restlessness is prejudice. As long as prejudice remains, warfare will continue, animosity and hatred will prevail. Therefore, if we seek to establish peace we must cast aside all these prejudices for otherwise it is impossible to find agreement and composure.
