What is the mission of saints as described in Chapter 4, and how do they interact with worldly life to achieve it?

As detailed in Chapter 4, the mission of saints is to perform the work of religion and awaken faith in the populace. They are not detached ascetics who shun the world entirely. Instead, the chapter uniquely states that 'Around the frame of Worldly Activity (Pravritti), they easily uplift the devotees.' This suggests that saints work within the context of everyday life to guide their followers. Their purpose is to fill the foundation of Renunciation (Nivritti) and build the temple of Ultimate Truth, effectively using worldly existence as a framework to guide people toward spiritual liberation. Once this specific work is fulfilled and their mission is complete, they conclude their incarnation.
