"It can tear every bond asunder, and hath the power to restore the force that hath spent itself and vanished…."

"... My object is none other than the betterment of the world and the tranquillity of its peoples. The well-being of mankind, its peace and security, are unattainable unless and until its unity is firmly established. This unity can never be achieved so long as the counsels which the Pen of the Most High hath revealed are suffered to pass unheeded.

Through the power of the words He hath uttered the whole of the human race can be illumined with the light of unity, and the remembrance of His Name is able to set on fire the hearts of all men, and burn away the veils that intervene between them and His glory. One righteous act is endowed with a potency that can so elevate the dust as to cause it to pass beyond the heaven of heavens. It can tear every bond asunder, and hath the power to restore the force that hath spent itself and vanished…."
