Etymology of Imam Hussein's Aza 
   The words Azadari and Majalis-e Aza have been exclusively used in connection with the remembrance ceremonies for the martyrdom of Imam Hussain. Majalis-e Aza, also known as Aza-e Husayn, includes mourning congregations, lamentations, matam and all such actions which express the emotions of grief and above all, repulsion against what Yazid stood for.
 The term majalis has both a grammatical meaning and a meaning which relates to Aza-e-Husayn. In its technical sense, a majalis is a meeting, a session or a gathering.
