From a devotee's perspective, what is the role and importance of a saint's incarnation during times of moral decline as outlined in Chapter 4?

From the viewpoint of a devotee, Chapter 4 portrays a saint's incarnation as a beacon of hope and salvation during dark times. When society is plagued by irreligion, when people are obsessed with lust and hunger, and when the path to ultimate well-being is obscured, the saint arrives to guide and protect. According to the chapter, saints descend to protect the humble, poor, and weak, and to uplift the distressed. They work to awaken faith and restore religion, providing a pathway for devotees to achieve spiritual upliftment. Their presence offers a direct means for self-upliftment when all other societal structures have failed.
