O people of the world!

O people of the world! The dawn of the Sun of Reality is assuredly for the illumination of the world and for the manifestation of mercy. In the assemblage of the family of Adam results and fruits are praiseworthy, and the holy bestowals of every bounty are abundant. It is an absolute mercy and a complete bounty, the illumination of the world, fellowship and harmony, love and union; nay, rather, mercifulness and oneness, the elimination of discord and the unity of whosoever are on the earth in the utmost of freedom and dignity. The Blessed Beauty said: "All are the fruits of one tree and the leaves of one branch." He likened the world of existence to one tree and all the souls to leaves, blossoms and fruits.

Therefore all the branches, leaves, blossoms and fruits must be in the utmost of freshness, and the bringing about of this delicacy and sweetness depends upon union and fellowship. Therefore they must assist each other with all their power and seek everlasting life. Thus the friends of God must manifest the mercy of the Compassionate Lord in the world of existence and must show forth the bounty of the visible and invisible King.
-- 'Abdu'l-Baha,
