…it hath been proven and made evident that these infinite
beings in this wondrous universe will discharge their functions properly only
when directed and controlled by that Universal Reality, so that order may be
established in the world. For example, interaction and co-operation between the
constituent parts of the human body are evident and indisputable, yet this does
not suffice; an all-unifying agency is necessary that shall direct and control
the component parts, so that these through interaction and co-operation may
discharge in perfect order their necessary and respective functions.
(‘Abdu’l-Baha,
’Tablet to August Forel’)
