Serve the people wholeheartedly

Our point of departure is to serve the people whole-heartedly and never for a moment divorce ourselves from the masses, to proceed in all cases from the interests of the people and not from one's self-interest or from the interests of a small group, and to identify our responsibility to the people with our responsibility to the leading organs of the Party.
