What is the significance of Damu Anna's story in the context of devotion to Sai?

The story of Damu Anna, though described as very short in Chapter 25, is presented as being very pure in its meaning and serves as a key lesson for devotees. Its significance lies in demonstrating a core principle: when a devotee has 'one-pointed faith,' Sai actively intervenes to ward off misfortunes and grant their desires. Damu Anna's experience of being blessed with sons after being childless is a tangible proof of this principle. The narrative is meant to fill the hearts of listeners with joy and reinforce the idea of the Guru-Mother as an 'Ocean of Mercy,' whose holy stories can burn away sins and make difficulties vanish.
