Now concerning nature, it is but the essential properties
and the necessary relations inherent in the realities of things. And though
these infinite realities are diverse in their character yet they are in the
utmost harmony and closely connected together. As one’s vision is broadened and
the matter observed carefully, it will be made certain that every reality is
but an essential requisite of other realities. Thus to connect and harmonize
these diverse and infinite realities an all-unifying Power is necessary, that
every part of existent being may in perfect order discharge its own function.
Consider the body of man, and let the part be an indication of the whole.
Consider how these diverse parts and members of the human body are closely
connected and harmoniously united one with the other. Every part is the
essential requisite of all other parts and has a function by itself. It is the
mind that is the all-unifying agency that so uniteth all the component parts
one with the other that each dischargeth its specific function in perfect
order, and thereby co-operation and reaction are made possible. All parts
function under certain laws that are essential to existence. Should that
all-unifying agency that directeth all these parts be harmed in any way there
is no doubt that the constituent parts and members will cease functioning
properly; and though that all-unifying agency in the temple of man be not
sensed or seen and the reality thereof be unknown, yet by its effects it
manifesteth itself with the greatest power.
(‘Abdu’l-Baha, ’Tablet to August
Forel’)
