What follows is my provisional translation (in other words, not official or authorized; see here for more) of a Tablet from Baháʼuʼlláh, the original text of which is published in Áthár-i-Qalam-i-Aʻlá, vol. 7, p. 4.
The Most Mighty, the All-Glorious
Verily, the Book of Dawn hath risen from the horizon of My Revelation, and through It the land hath been illumined. This is the day in which all things speak forth, saying: “The kingdom is God’s, the Incomparable, the Unrestrained!” Burn ye the veils of vain imaginings with this resplendent light, which hath emerged from the bosom of the Lord of majesty and might. Is there any doubt about His sovereignty? No, by the Dawning-Place of the Unseen! Can His command ever be exhausted? No, by the Lord of the Day of Judgment!
Every tree hath been stirred through the breezes of the Almighty; yet, the hearts are burdened with a strange weight, save those who have attained unto that which hath gushed out from this Ocean, which hath encompassed all created things. They who have been inebriated with the wine of recognition can neither be shut out as by a veil, nor deterred by the influence of such as have disbelieved in God, Who causeth the night to return upon the day, and the day to return upon the night. Make thy lamp My love, thy companion My remembrance, and thy desire that which is desired by God, the Lord of the Day of Resurrection.
