Allama Dr. Muhammad Iqbal experienced progressive & constructive development in his Poetry & thought with the passage of time.
As Knowledge increases wonder deepens.
One can easily realize the difference between Iqbal's Juvenile poetry & Iqbal's Poetry before his death
."Asrar-O-Ramooz" is Iqbal's one of the finest poetry before his death which reveals Iqbal's wonder.
Asar-o-Ramooz:
He said,
Haidri Faqar hai na Daulat-e-Usmani hai.
Tum ko Aslaaf se kya nisbat-e-Rohani hai.
Meaning:
"O Muslims! neither you possess the wisdom(Faqar) of Ali nor the wealth of Usman - then what kind of metaphysical relations you claim with your ancestors."
He advised the Muslims,
Mera tareeq ameeri nahin faqeeri he.
Khudi na beich, ghareebi mein naam peida kar.
Meaning:
" I follow the path of wisdom(faqeeri) not wealth , don't sell Your KHUDI(conscience) , Acquire fame & excellence through poverty."
