What does Chapter 4 say about the selfless nature and ultimate mission of saints?

According to the teachings in Chapter 4, saints are described as being naturally liberated souls whose incarnations are purely for the sake of others, with no personal self-interest. Their primary mission is to uplift the distressed and protect the humble, poor, and weak. They work to establish the foundation of Renunciation (Nivritti) and build the temple of Ultimate Truth. By performing the work of religion and awakening faith in people, they help devotees navigate worldly activities while progressing spiritually. Once their specific work is fulfilled, they conclude their incarnation.
