The message of the saints.
"What was the message that these dead people carried, and what are we supposed to draw from their example?
Their message is that one who seeks the pleasure of Allah and strives for his existence to be useful in the way of Allah, in the pursuit of the highest divine purposes in this world, must deny himself in the face of purposes of a divine nature. It is not some kind of duty that is beyond human ability."
From the speech of the martyred Seyyed Ali Khamenei (bad) on the commemoration of the martyrs.
