Strike with all thy powers in diffusing the spirit of real
union among the people, so that all who are on earth become one family, loving,
united, agreed, bound by the bonds of love and united with all harmony in all
things and conditions. This is the greatest happiness of the human race in the
world of possibilities and the cause of attaining to all hopes and reaching
unto the Supreme Kingdom, after ascending unto the world of God.
- 'Abdu’l-Baha (Baha’i News, no.11, April 1926)
