To promote knowledge is thus an inescapable duty imposed on every one of the friends of God.
Abdu'l-BaháThe 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.
Abdu'l-BaháBe ye a refuge to the fearful; bring ye rest and peace to the disturbed; make ye a provision for the destitute; be a treasury of riches for the poor; be a healing medicine for those who suffer pain; be ye doctor and nurse to the ailing; promote ye friendship, and honour, and conciliation, and devotion to God, in this world of non-existence.
Abdu'l-Bahá
