Know all mankind of all nations, sects and tribes as your kith and kin. Consider not their deeds, but only God. Seek your reward from Him and not from them. Know the aged of all nations as your fathers, the juveniles as your brothers and the children as your own. No matter what lack of courtesy or what severe persecution or stern expressions of hate and unfathomable enmity you receive, you must have no excuse like the following: "So and so has spoken unkindly about me," "So and so has not done me justice," -- nay, rather you must have no excuse but live according to the Divine Teachings, whether humanity prove agreeable or disagreeable, whether humanity prove hateful or loving, whether it receives you or casts you out, so that perchance you may be assisted in hoisting the standard of peace and pitching the Tabernacle of Oneness and solidarity of the world of humanity -- so that this temporal life may ultimate in the Life Everlasting, and this darkness of ignorance which has pervaded the whole world may be converted into the illumination of guidance. So that material man may become celestial, and the earthly souls become the heavenly souls; that the blind may become perceptive, the deaf attentive, the ignorant wise, the dead arise, so that, in fact, the Kingdom of God in the world of humanity may pitch its Canopy and its Tabernacle in the utmost glory. 
- ‘Abdu’l-Baha  (From a Tablet, Star of the West, vol. 5. No. 9, August 20, 1914)
