Based on Chapter 25, what is the primary purpose of narrating the stories of Sai Baba?

Chapter 25 clarifies that the purpose of narrating Sai Baba's stories is to delight his devotees and awaken them spiritually. The author, feeling unqualified, states that Sai himself inspired the writing of the Shri Sai Satcharitra for the salvation of his devotees. The chapter describes the collection of stories as a "Shed of Nectar-like Sai Stories" that can help devotees ward off the heat of worldly existence. Furthermore, listening to these holy stories with a focused mind is said to burn away the sins of the Kali age. The narratives are meant to show Sai's love and mercy, as exemplified by the introduction of Damu Anna's story.
