" ... O mother of the world and fountain of light unto all its peoples ..."

"O thou whose face is turned towards Me! As soon as thine eyes behold from afar My native city (Ṭihrán), stand thou and say: I am come to thee out of the Prison, O Land of Tá, with tidings from God, the Help in Peril, the Self-Subsisting. I announce unto thee, O mother of the world and fountain of light unto all its peoples, the tender mercies of thy Lord, and greet thee in the name of Him Who is the Eternal Truth, the Knower of things unseen. I testify that within thee He Who is the Hidden Name was revealed, and the Unseen Treasure uncovered. Through thee the secret of all things, be they of the past or of the future, hath been unfolded.

O Land of Tá! He Who is the Lord of Names remembereth thee in His glorious station. Thou wert the Day Spring of the Cause of God, the fountain of His Revelation, the manifestation of His Most Great Name—a Name that hath caused the hearts and souls of men to tremble. How vast the number of those men and women, those victims of tyranny, that have, within thy walls, laid down their lives in the path of God, and been buried beneath thy dust with such cruelty as to cause every honored servant of God to bemoan their plight."
