Iranian poet Saadi wrote a poem eight centuries ago that later became a motto on the entrance of the United Nations building.

Saadi eloquently manifested:

The sons of Adam are limbs of each other,

Having been created of one essence.

When the calamity of time affects one limb

The other limbs cannot remain at rest.

If thou hast no sympathy for the troubles of others

Thou art unworthy to be called by the name of a human.

since “old stuff” is esoteric (even when translated), here it is EXPLAINED!

Human beings are members of a whole, 

In creation of one essence and soul. 

If one member is afflicted with pain, 

Other members uneasy will remain. 

If you have no sympathy for human pain, 

The name of human you cannot retain.
