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.
چو عضوى به درد آورد روزگار....... دگر عضوها را نماند قرار
تو کز محنت دیگران بی غمی.......... نشاید که نامت نهند آدمی
The irony is that, this poem is used to grace the entrance to the Hall of Nations of the UN building in New York, with the call for breaking all barriers.
Where are you Saadi to see that how little and strange your invaluable thoughts have become in our world!
