Rejoice with exceeding gladness, O people of Bahá, as ye call to remembrance the Day of supreme felicity, the Day whereon the Tongue of the Ancient of Days hath spoken, as He departed from His House, proceeding to the Spot from which He shed upon the whole of creation the splendors of His name, the All-Merciful. God is Our witness. Were We to reveal the hidden secrets of that Day, all they that dwell on earth and in the heavens would swoon away and die, except such as will be preserved by God, the Almighty, the All-Knowing, the All-Wise.
