[isotelesis]

Very interesting explanation Chris.

بنی آدم اعضای یک پیکرند
که در آفرينش ز یک گوهرند

چو عضوى به درد آورد روزگار
دگر عضوها را نماند قرار

تو کز محنت دیگران بی غمی
نشاید که نامت نهند آدمی

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.

Alternative translation by Dr. Iraj Bashiri:

Of One Essence is the Human Race,
Thusly has Creation put the Base.
One Limb impacted is sufficient,
For all Others to feel the Mace.
The Unconcern'd with Others' Plight,
Are but Brutes with Human Face.

- Sa'di of Shiraz
