How does the account of Damu Anna illustrate the concept of Sai being an 'Ocean of Mercy'?

The story of Damu Anna serves as a perfect illustration of Sai Baba as an 'Ocean of Mercy,' a term used within the text itself. As Chapter 25 explains, the Guru-Mother's compassionate nature is revealed through this narrative. Damu Anna, a prosperous but sorrowful childless man, placed his faith in Sai. In response, Sai removed his suffering and granted his desire for sons. This act of grace, which transformed a devotee's misfortune into joy, showcases the boundless compassion and love Sai has for His followers. The story is intentionally shared to demonstrate that with one-pointed faith, Sai's mercy flows to ward off calamities and fulfill wishes, proving He is indeed an 'Ocean of Mercy.'
