How is Damu Anna's story used to illustrate Sai Baba's relationship with his devotees?

The story of Damu Anna, as introduced in Chapter 25, serves as a powerful illustration of Sai Baba's protective love and mercy towards his followers. The chapter explicitly states that "Once one-pointed faith is established, Sai wards off all the misfortunes of that devotee" and "grants the desired objects and removes their suffering." Damu Anna's narrative is presented as a direct report to demonstrate this principle. He was a devout follower who was blessed with sons after being childless, showcasing how the "Guru-Mother is an 'Ocean of Mercy.'" His story is meant to fill listeners' hearts with joy and reinforce the idea of Sai's readiness to protect those who are devoted to His feet.
