How is Sai Baba's character and state of being portrayed in Chapter 5?

In Chapter 5, Sai Baba is portrayed as a figure of profound humility and desirelessness. Despite his spiritual stature, he maintained the attitude of being a disciple in the presence of a Fakir who once considered himself a Guru, teaching the lesson "His Guruship to him, and my discipleship to me." The text notes that both the young and old were amazed by his desireless state at a young age. Chapter 5 also delves into the nature of a truly wise person, explaining that their actions are the result of previous karma and they reside in a state of non-duality, free from the burden of karma and the sense of being the 'doer' of actions.
