"It is necessary that each Marxist-Leninist understand that he can contribute to Marxism-Leninism with an atom of his experience, that every solution he finds, every experience he acquires, in the act of solving a problem, will be one more experience with which he enriches Marxism-Leninism, because Marxism-Leninism has been enriched so much precisely by the experience of millions and millions of Marxist-Leninists acting in the reality of life."
