"Whether one is correct or not in the ideological and political line determines everything. With a correct Party line, we will have everything. If we do not have people, we will get them; if we do not have guns, we will get them; if we do not have political power, we will get it. However, if the political line is not correct, we will lose everything we have. The line is the key link; once the key link is grasped, every problem will be solved."
Mao Zedong, talk with responsible comrades during an inspection tour, August-September 1971.
