…as the human body in this world, which is outwardly
composed of different limbs and organs, is in reality a closely integrated,
coherent entity, similarly the structure of the physical world is like unto a
single being whose limbs and members are inseparably linked together. Were one to observe with an eye that
discovereth the realities of all things, it would become clear that the greatest
relationship that bindeth the world of being together lieth in the range of
created things themselves, and that co-operation, mutual aid and reciprocity
are essential characteristics in the unified body of the world of being,
inasmuch as all created things are closely related together and each is
influenced by the other or deriveth benefit therefrom, either directly or indirectly.
- ‘Abdu’l-Baha (The Compilation of Compilations vol. I, Conservation of the
Earth's Resources)
