Him Who hath branched from this mighty Stock

'Abdu'l-Baha in a garden in Haifa

O people of the world! When the Mystic Dove will have winged its flight from its Sanctuary of Praise and sought its far-off goal, its hidden habitation, refer ye whatsoever ye understand not in the Book to Him Who hath branched from this mighty Stock [‘Abdu’l-Baha]. 
- Baha'u'llah  (The Kitab-i-Aqdas)
