What is the stated purpose of including stories like Damu Anna's in the Shri Sai Satcharitra?

Chapter 25 frames the story of Damu Anna not just as a historical account, but as a teaching tool to illustrate a core message. The purpose is to show that once a devotee establishes one-pointed faith, Sai wards off all their misfortunes. The author states that listening to these holy stories with reverence fills the listener's heart with joy and can burn away the sins of the Kali age. The entire Satcharitra is described as a 'Shed of Nectar-like Sai Stories' that helps devotees ward off the heat of worldly existence. Therefore, Damu Anna's story serves as a specific, pure, and potent example of how the 'Guru-Mother is an Ocean of Mercy.'
