What follows is my provisional translation (in other words, not official or authorized; see here for more) of a Tablet from ʻAbduʼl-Bahá written on the night of Yaldá (the winter solstice), the original text of which is published in Muntakhabátí az Makátíb-i-Ḥaḍrat-i-ʻAbduʼl-Bahá, vol. 3, pp. 216–217 (passage no. 294).
O friends of God! Though the Sun of Truth hath been obscured behind the clouds of glory; though these clouds have interposed themselves as veils, and the gloom of estrangement hath enveloped the earth; though every eye be in tears, every heart be afflicted with a burning torment, and every soul be sorely distressed; though the fire of bitter remorse hath flared up, and so consumed the vitals of men that they, for the most part, have grown weary of living, such that they now yearn for the heavenly rose-garden—yet on this night, the night of Yaldá, the fire of the love of God burneth so fiercely within the friends that its heat hath warmed away the coldness of remoteness, and its flame hath devoured every trace of darkness. The Lord be praised, for the loved ones of God are aglow, even as brightly burning candles, and serve as guiding stars unto every gathering. They have kindled a fervid flame, and ignited a fresh fire. They have succeeded in rendering services at the sacred threshold; blessed are they, and glad tidings be theirs, both in the beginning and in the end.
O friends of God! Cherish with heart and soul this hope, and supplicate the Ever-Forgiving Lord that you may be aided to fulfill it: that you may each become a brilliant star in the firmament of guidance, a fruitful tree in the Most Glorious Paradise, a bright candle in the assemblages of spiritual ones, and an ornament of every gathering devoted to the divine.
O friends of ʻAbduʼl-Bahá! Our days are numbered—our lives destined to end. Should one not strive to exalt the Word of God, unbearable regret would he face in the end, and remoteness and loss would he come to feel. While there is yet life within you, then, you must be cup-bearers who proffer the spiritual wine. Strive with all your might, that you may cause leaves to flourish and fruits to be borne; that you may make buds to blossom and succeed in securing sustenance for yourselves; that the fire of love may enkindle you with a flame that will reach the Concourse on High—a flame that shall cause the denizens of the All-Glorious Kingdom to rejoice with exceeding gladness, move them to great rapture and ecstasy, and rouse them to fervent delight.
Upon you all be salutations and praise.
