One night, Shoghi Effendi asked me a question, which I could not answer, nor did I understand its significance at the time. Shoghi Effendi asked me: "Since after the martyrdom of the Báb the authority of the Faith was passed on to Bahá'u'lláh, and after His passing to 'Abdu'l-Bahá, to whom was it transferred after the ascension of 'Abdu'l-Bahá? I answered, of course, Shoght Effendi. He said no. I then said, the Guardian. He again shook his head. I then ventured the Universal House of Justice. He again said no, and I could see from his expression that he was disappointed with my inability to answer his question. Then he asked, are the friends not reading my letters? The answer he said, is clearly stated in The Dispensation of Bahá'u'lláh. It is divided into four parts: Bahá'u'lláh, the Báb, 'Abdu'l-Bahá and the fourth part is entitled "The World Order of Bahá'u'lláh", which is the answer to his question". [TG72]

Note: In actual fact, the fourth part of The Dispensation of Bahá'u'lláh is entitled "The Administrative Order" The explanation is in The Dispensation of Bahá'u'lláh, (BPT-Wilmette 1970) page 55-56.
