You are well aware, praised
be the Lord, that both interaction and co-operation are evident and proven
amongst all beings, whether large or small. In the case of large bodies
interaction is as manifest as the sun, whilst in the case of small bodies,
though interaction be unknown, yet the part is an indication of the whole. All
these interactions therefore are connected with that all-embracing power which
is their pivot, their centre, their source and their motive power.
For instance, as we have
observed, co-operation among the constituent parts of the human body is clearly
established, and these parts and members render services unto all the component
parts of the body. For instance, the hand, the foot, the eye, the ear, the
mind, the imagination all help the various parts and members of the human body,
but all these interactions are linked by an unseen, all-embracing power, that
causeth these interactions to be produced with perfect regularity. This is the
inner faculty of man, that is his spirit and his mind, both of which are
invisible.
(‘Abdu’l-Baha, ’Tablet to August Forel’)
