The basis of the teaching of Bahá’u’lláh is the Unity of Mankind, and his greatest desire was that love and goodwill should live in the heart of men.

As He exhorted the people to do away with strife and discord, so I wish to explain to you the principal reason of the unrest among nations. The chief cause is the misrepresentation of religion by the religious leaders and teachers. They teach their followers to believe that their own form of religion is the only one pleasing to God, and that followers of any other persuasion are condemned by the All-Loving Father and deprived of His Mercy and Grace. Hence arise among the peoples, disapproval, contempt, disputes and hatred. If these religious prejudices could be swept away, the nations would soon enjoy peace and concord.
