What spiritual benefits does Sai Baba say will come from writing or listening to his life story?

In Chapter 3, Sai Baba explicitly details the spiritual rewards of engaging with his life story, or Charitra. He gives his full permission for it to be written, promising the author that through this act, "the faults of ignorance (Avidya) will be destroyed." For those who listen to the stories with devotion, he states that their attachment to worldly affairs will fade away. He beautifully describes that "waves of the nectar of devotion and love will rise upon the ocean of listening," and by diving into this, one can find gems of knowledge. This process is designed to bring natural joy to his devotees.
