Kabhi kisi ko muqammal jahan nahi milta,
kisi ko zameen to kisi ko aasmaan nahi milta
(Nobody ever gets it all in this universe. If one doesn't receive the ground below, someone else doesn't get the sky above.)
PS This is just a candid translation of this amazing piece of poetry. If someone else can do justice to the sentiment and the words and come up with a better translation, let me know.
