It is incumbent upon the Aghsan, the Afnan and My kindred to turn, one and all, their faces towards the Most Mighty Branch. Consider that which We have revealed in Our Most Holy Book: "When the ocean of My presence hath ebbed and the Book of My Revelation is ended, turn your faces toward Him Whom God hath purposed, Who hath branched from this Ancient Root." The object of this sacred verse is none other except the Most Mighty Branch ('Abdu'l-Bahá). Thus have We graciously revealed unto you our potent Will, and I am verily the Gracious, the All-Powerful.
(Baha’u’llah, cited by Shoghi Effendi in ‘The World Order of Bahá'u'lláh - Selected Letters’; The Compilation of Compilations vol. I, The Covenant)
