How does the author of the Sai Satcharitra frame the story of Damu Anna, and what is its stated purpose for the reader?

The author introduces the story of Damu Anna in Chapter 25 not merely as a tale, but as a testament to Sai's divine power and mercy. It is presented as a "report that shows Sai's love for His devotees," promising that listening to it will bring joy to the listener's heart. The author urges the audience to listen with a focused mind, suggesting the story is a "Shed of Nectar-like Sai Stories" that can ward off the heat of worldly existence. The stated purpose, as explained in Chapter 25, is to demonstrate how the "Guru-Mother is an 'Ocean of Mercy'" and to show how listening to these holy stories can help burn away the sins of the age and make one's difficulties vanish.
