That thread may be of use to you. It isn't from an Islamic perspective, but it still sheds light on the subject.
Not surprisingly, it's a technical religious term. Mahdaviat derives from mahdi, Arabic for "rightly-guided one," a major figure in Islamic eschatology. He is, explains the Encyclopaedia of Islam, "the restorer of religion and justice who will rule before the end of the world." The concept originated in the earliest years of Islam and, over time, became particularly identified with the Shi‘ite branch. Whereas "it never became an essential part of Sunni religious doctrine," continues the encyclopedia, "Belief in the coming of the Mahdi of the Family of the Prophet became a central aspect of the faith in radical Shi‘ism," where it is also known as the return of the Twelfth Imam.
Mahdaviat means "belief in and efforts to prepare for the Mahdi."
He often raises the topic, and not just to Muslims. When addressing the United Nations in September, Mr. Ahmadinejad flummoxed his audience of world political leaders by concluding his address with a prayer for the Mahdi's appearance: "O mighty Lord, I pray to you to hasten the emergence of your last repository, the Promised One, that perfect and pure human being, the one that will fill this world with justice and peace."
Mahdaviat has direct and ominous implications for the U.S.-Iran confrontation, says an Ahmadinejad supporter, Hamidreza Taraghi of Iran's hard-line Islamic Coalition Society. It implies seeing Washington as the rival to Tehran and even as a false Mahdi. For Mr. Ahmadinejad, the top priority is to challenge America, and specifically to create a powerful model state based on "Islamic democracy" by which to oppose it. Mr. Taraghi predicts trouble ahead unless Americans fundamentally change their ways.
