The podcast episodes discuss the importance of the mass line as a key organizational principle within the Marxist-Leninist-Maoist tradition. The mass line emphasizes the need for a revolutionary party to stay closely connected to the masses, learning from their experiences and struggles, and then using this knowledge to develop effective strategies for achieving lasting revolutionary change.

For example, episode "What Is To Be Done? Understanding Communist Strategy" explores how the mass line contrasts with spontaneous protests, arguing that a disciplined vanguard party is crucial for uniting struggles and going beyond mere reforms. Similarly, episode [BEST OF] On Contradiction - Mao" analyzes Mao's mass line as a dialectical approach to organizing the masses.

Episode "Mass Struggle: Misconceptions and Distortions of the Mass Line" is entirely focused on discussing common misunderstandings and errors in applying the mass line, such as bourgeois populism and sectarian dogmatism.
