What does Chapter 4 of the Sai Satcharitra say about why saints like Sai Baba come to Earth?

Chapter 4 of the Sai Satcharitra explains that saints incarnate during times of significant religious and societal decay. According to the text, they appear when people lose respect for religious traditions, when sectarian hatred grows, and when individuals become solely focused on worldly happiness like wealth and family, forgetting the ultimate spiritual goal. As detailed in Chapter 4, saints descend to this earth to awaken religion, protect the humble, the poor, and the weak, and destroy irreligion. Their incarnation is described as being purely for the sake of others, with no self-interest involved, to uplift the distressed and guide them back to the right path.
