O ye who are steadfast in the Covenant! The pilgrim hath made mention of each one of you, and hath asked for a separate letter addressed to each, but this wanderer in the wilderness of God’s love is withheld from correspondence by a thousand preoccupations and concerns; and since out of the easts and the wests of the earth there poureth a mounting flood of letters upon him, it would be impossible to send a separate letter to each one, wherefore this one letter is addressed to each of you, that it may, as sealed wine, rejoice your souls and warm your hearts.
Wherefore, O ye beloved of the Lord, bestir yourselves, do all in your power to be as one, to live in peace, each with the others: for ye are all the drops from but one ocean, the foliage of one tree, the pearls from a single shell, the flowers and sweet herbs from the same one garden. And achieving that, strive ye to unite the hearts of those who follow other faiths.
For one another must ye give up even life itself. To every human being must ye be infinitely kind. Call none a stranger; think none to be your foe. Be ye as if all men were your close kin and honoured friends. Walk ye in such wise that this fleeting world will change into a splendour and this dismal heap of dust become a palace of delights. Such is the counsel of ‘Abdu’l-Bahá, this hapless servant.
