Sir! We need you desperately at this moment, sir! All your contemporaries have passed away. Yet you remain immortal even in death. Your grave is an inspiration to us. We are invigorated in your spirit
You, too, will eventually succumb to death, according to the laws of nature. But as long as you live, live with a backbone. Support just demands, take to the streets, and stand as a shield for the students. You will receive genuine honor and respect. You will not fade into the annals of time upon your death. You will live forever as a Shamsuzzoha. Dying as a 'Shamsuzzoha' is far more joyous, honorable, and glorious.[11][12]
