Forty years of thy precious existence have expired by Sadi

Forty years 
of thy precious existence 
have expired; 

Yet thy life hath 
not passed beyond childhood.

Thou hast spent
all in lust and licence;

Not a moment hast thou acted
according to righteousness.

Rely not upon
unstable life;

Be not confident
that thou art safe

from the sport
of fortune.

~ Sadi's Scroll of Wisdom,
