An excellent short video on the significance of Azadari or mourning for the martyrs of Karbala and tyranny against the progeny of Prophet Mohammad (SAAS). It is highly informative video and contains many answers about why Shia communities throughout the world commemorate the events of the tragedy of Karbala? What is the background of mourning, and the history of crying, and matam or "self-flagellation" in the form of striking one's face and chest, or using chains and blades in matam. It takes the viewer through different stages of the commemoration of tragic events and ends beautifully with the couplet that "In the Murder of Hussain, Indeed is the death of Yazid; Thus Karbala has revived Islam".
