The effects of the “undying Fire which the Lord of the Kingdom hath kindled in the midst of the holy Tree”

O my friend! The undying Fire which the Lord of the Kingdom hath kindled in the midst of the holy Tree is burning fiercely in the midmost heart of the world. The conflagration it will provoke will envelop the whole earth. Its blazing flames will illuminate its peoples and kindreds. All the signs have been revealed; every prophetic allusion hath been manifested. Whatever hath been enshrined in all the Scriptures of the past hath been made evident. To doubt or hesitate is no more possible . . . Time is pressing. The Divine Charger is impatient, and can tarry no longer. Ours is the duty to rush forward and, ere it is too late, win the victory. What more shall I say? What else can my pen recount? So loud is the call that reverberates from the Abha Kingdom that mortal ears are well-nigh deafened with its vibrations. The whole creation, methinks, is being disrupted and is bursting asunder through the shattering influence of the Divine summons issued from the throne of glory. More than this I cannot write. 

- ‘Abdu’l-Baha  (Quoted by Shoghi Effendi in ‘The World Order of Baha’u’llah’)
