WE ALL ARE ONE SINGLE HUMAN FAMILY.
Humans are peers of a united race,
Thus in creation, share the same base.
If one is affected with pain,
Others share the faith & spirit of same. ...
When you are indifferent to this pain,
You shall not earn the Humans’ name.
بنى آدم اعضای یک پیکرند
که در آفرینش 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
By Saadi Shirazi year 1240 Shiraz Persia.

Saadi also wrote : The beloved of the Almighty are: the rich who have the humility of the poor, and the poor who have the magnanimity of the rich.
He who is a slave to his stomach seldom worships "God".. [This aphorism was also popular in ancient India ei an empty stomach or one who is thinking of eating always, can not think of worshipping.]
Saadi added this sarcastically : When the belly is empty, the body becomes spirit; and when it is full, the spirit becomes body.
