How does Chapter 4 describe the nature of saints and their mission to uplift humanity?

In Chapter 4, saints are portrayed as being naturally liberated souls whose incarnations are purely for the benefit of others, with no self-interest involved. Their primary mission is to counter the decay of religion and protect the social and spiritual order. The text explains that they come to uplift the distressed, the poor, and the weak. Their method involves filling the foundation of Renunciation (Nivritti) and building the temple of Ultimate Truth, thereby easily uplifting devotees. As Chapter 4 states, they perform the work of religion and awaken faith, and once their specific mission is fulfilled, they conclude their incarnation.
