Epistle to the Son of the Wolf — Paragraph 209

O Shaykh! Great is the Cause, and great the Announcement! Patiently and calmly ponder thou upon the resplendent signs and the sublime words, and all that hath been revealed in these days, that haply thou mayest fathom the mysteries that are hid in the Books, and mayest strive to guide His servants. Hearken with thine inner ear unto the Voice of Jeremiah, Who saith: "Oh, for great is that Day, and it hath no equal." Wert thou to observe with the eye of fairness, thou wouldst perceive the greatness of the Day. Incline thine ear unto the Voice of this All-Knowing Counsellor, and suffer not thyself to be deprived of the mercy that hath surpassed all created things, visible and invisible. Lend an ear unto the song of David. He saith: "Who will bring me into the Strong City?" The Strong City is ‘Akká, which hath been named the Most Great Prison, and which possesseth a fortress and mighty ramparts.
