This part narrates the very oft-quoted incident between Shams Tabrezi and Maulana Rumi, followed by Iqbal disparaging modern knowledge and education as it is devoid of love ('ishq). I am too exhausted due to IRL stuff to write much more, but let not my brief description fool you into thinking that I did not like it. It was good. But question tho: what does the word 'ibrat mean here in this sher?
گلستانی لاله زار عبرتی
چون گل کاغذ سراب نکهتی
