How does Chapter 4 portray the selfless nature and ultimate mission of saints?

Chapter 4 of the Sai Satcharitra emphasizes that saints are naturally liberated beings whose incarnations are purely for the benefit of others, devoid of any self-interest. Their purpose is to uplift the distressed and protect the weak. The text poetically describes their mission as filling the foundation of Renunciation (Nivritti) and building the temple of Ultimate Truth. As Chapter 4 explains, they work to perform the duties of religion and awaken faith among the people. Once their specific work is fulfilled and their mission is complete, they conclude their incarnation.
