"Unveil Thy face, and manifest the beauty of the black-eyed Damsel, and suffer not the servants of God to be deprived of the light of Thy shining countenance."

Reverse of Medallion of 'Abdu'l-Bahá by Louis Potter

"Say: Step out of Thy holy chamber, O Maid of Heaven, inmate of the Exalted Paradise! Drape thyself in whatever manner pleaseth Thee in the silken Vesture of Immortality, and put on, in the name of the All-Glorious, the broidered Robe of Light. Hear, then, the sweet, the wondrous accent of the Voice that cometh from the Throne of Thy Lord, the Inaccessible, the Most High. Unveil Thy face, and manifest the beauty of the black-eyed Damsel, and suffer not the servants of God to be deprived of the light of Thy shining countenance. Grieve not if Thou hearest the sighs of the dwellers of the earth, or the voice of the lamentation of the denizens of heaven. Leave them to perish on the dust of extinction. Let them be reduced to nothingness, inasmuch as the flame of hatred hath been kindled within their breasts. Intone, then, before the face of the peoples of earth and heaven, and in a most melodious voice, the anthem of praise, for a remembrance of Him Who is the King of the names and attributes of God. Thus have We decreed Thy destiny. Well able are We to achieve Our purpose. 

Beware that Thou divest not Thyself, Thou Who art the Essence of Purity, of Thy robe of effulgent glory. Nay, enrich Thyself increasingly, in the kingdom of creation, with the incorruptible vestures of Thy God, that the beauteous image of the Almighty may be reflected through Thee in all created things and the grace of Thy Lord be infused in the plenitude of its power into the entire creation. 

If Thou smellest from anyone the smell of the love of Thy Lord, offer up Thyself for him, for We have created Thee to this end, and have covenanted with Thee, from time immemorial, and in the presence of the congregation of Our well-favored ones, for this very purpose. Be not impatient if the blind in heart hurl down the shafts of their idle fancies upon Thee. Leave them to themselves, for they follow the promptings of the evil ones."
