The diversity in the human family should be the cause of love and harmony, as it is in music where many different notes blend together in the making of a perfect chord. If you meet those of different race and colour from yourself, do not mistrust them and withdraw yourself into your shell of conventionality, but rather be glad and show them kindness. Think of them as different coloured roses growing in the beautiful garden of humanity, and rejoice to be among them.
Likewise, when you meet those whose opinions differ from your own, do not turn away your face from them. All are seeking truth, and there are many roads leading thereto. Truth has many aspects, but it remains always and forever one. Do not allow difference of opinion, or diversity of thought to separate you from your fellow-men, or to be the cause of dispute, hatred and strife in your hearts. Rather, search diligently for the truth and make all men your friends.
Every edifice is made of many different stones, yet each depends on the other to such an extent that if one were displaced the whole building would suffer; if one is faulty the structure is imperfect.
Bahá'u'lláh has drawn the circle of unity, He has made a design for the uniting of all the peoples, and for the gathering of them all under the shelter of the tent of universal unity. This is the work of the Divine Bounty, and we must all strive with heart and soul until we have the reality of unity in our midst, and as we work, so will strength be given unto us. Leave all thought of self, and strive only to be obedient and submissive to the Will of God. In this way only shall we become citizens of the Kingdom of God, and attain unto life everlasting.(Abdu'l-Baha, Paris Talks, p. 53)
