What does Chapter 4 say about the state of humanity when people turn away from spiritual goals, and how do saints respond?

Chapter 4 of the Sai Satcharitra describes a grim state for humanity when spiritual goals are forgotten. It states that when people consider worldly things like wealth, status, sons, and spouses as the only source of happiness and turn away from the ultimate goal (Paramartha), they lose their chance for ultimate well-being. This leads to a loss of long life, health, and prosperity, with people wandering about obsessed only with lust and hunger. In response to this decay, as the chapter explains, saints incarnate to awaken religion and provide a path for self-upliftment, protecting the humble and destroying irreligion to restore balance.
