“Aghsán” (plural of Ghusn) is the Arabic word for “Branches”. This term is used by Bahá’u’lláh to designate His male descendants. It has particular implications not only for the disposition of endowments but also for the succession of authority following the passing of Bahá’u’lláh (see note 145) and of ‘Abdu’l-Bahá. Bahá’u’lláh, in the Book of His Covenant, appointed ‘Abdu’l-Bahá, His eldest son, as the Centre of His Covenant and the Head of the Faith. ‘Abdu’l-Bahá, in His Will and Testament, appointed 197 Shoghi Effendi, His eldest grandson, as the Guardian and Head of the Faith.

This passage of the Aqdas, therefore, anticipates the succession of chosen Aghsán and thus the institution of the Guardianship and envisages the possibility of a break in their line. The passing of Shoghi Effendi in 1957 precipitated the very situation provided for in this passage, in that the line of Aghsán ended before the Universal House of Justice had been established (see note 67).
