Dr Iqbal and Anwar Shah Kashmiri

ہزاروں سال نرگس اپنی بے نوری پہ روتی ہے
بڑی مشکل سے ہوتا ہے چمن میں دیدہ ور پیدا

Dr. Sir Mohammad Iqbal has once said that it's enough for me to declare and accept that Islam is the ultimate reality and final truth, because I know a man who's really an authority and a man of enough wisdom and knowledge and cannot be defeated by any rational or any other means, has accepted and is practicing on the same Islam. Since he has accepted I've no choice other than to accept the same. After his death Dr Iqbal has written the above poetic verse on his authority and in his love. This's a special bond and the acceptance shown by the legendary figures like Iqbal for his legendary guide Allama Anwar Shah(RA).
This's how a real man shows respect and love for his guide or mentor.
