What is the author's stated purpose for writing Chapter 18, and what does he ask of the reader?

In Chapter 18, the author explicitly states his intention to narrate a "sweet tale" about the grace bestowed upon him by Sai Baba. After briefly recapping the theme of the previous chapter, he promises to narrate this personal story with accuracy. The author's primary request to the audience is to listen with respect and a calm mind. He notes that when a listener is attentive, the speaker feels enthusiasm, and a "spring of love overflows," creating a joyful experience for both. This emphasis on attentive listening is presented as being for the listener's own benefit, so they may experience Baba's guidance in their hearts, as detailed in Chapter 18.
