"Marxism-Leninism is the acme of human thought in our time. It not only explains the world thoroughly, but transforms it radically. It is the beacon lighting the path of the international working class, the oppressed peoples and the whole of progressive man-kind, who are struggling to rid themselves of all oppression and exploitation and to build a new world, a world of genuine peace, freedom and happiness."
January 1, 1970
