…even 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.
- 'Abdu’l-Baha (From a Tablet, The Compilation of Compilations vol. I,
Conservation of the Earth's Resources)
