The technique describes how leaders must effectively organize the masses, which are composed of “relatively active, intermediate, and relatively backward” groups (“The Mass Line” 417) . Mao proposes that a leader make those who are relatively active a “leadership core” and “rely on this leading group to raise the level of the intermediate elements.” Without it, he says, a leader can't make a broad call to action effective. Without this deep connection with the masses, Mao states that a “leadership becomes bureaucratic and separated from the masses” and, therefore, that the leadership will fail to create widespread movements. This line of thinking is crucial to understanding Mao's ability to mobilize masses of people to realize his goals organically, that is, by inspiring people rather than issuing orders based on political authority alone. It also shows that Mao was very tired of the development of an inefficient bureaucracy under his administration, which later led him to promote the Hundred Flowers Policy among other political movements. Overall, Mao is able to impose his will because the people have rallied behind him, supporting and carrying out his policies, as well as putting pressure on Mao's policies.
