How does the author of the Sai Satcharitra frame the story of Damu Anna and for what purpose?

The author introduces the story of Damu Anna as a clear demonstration of Sai's love and protective nature towards His devotees. In Chapter 25, it is presented as a report meant to fill the reader's heart with joy and show how Sai, the "Guru-Mother," is an "Ocean of Mercy." The story's purpose is to illustrate a key theme: once a devotee establishes one-pointed faith, Sai removes their suffering and grants their desires. The author calls the story "very pure in its meaning" and suggests that by giving it attention, one's own difficulties will vanish.
