What observation does the text make about human nature while describing Amani's focus on receiving money?

While describing the scene where the young girl Amani's mind is fixated on the rupees she wants from Baba, Chapter 29 makes a broader philosophical point about human nature. The scripture reflects, "This was the child-like nature of Amani. The same longing exists in elders too - the running about is only for self-interest; only rare ones have the sentiment for the highest good." This commentary uses Amani's innocent, singular focus on material gain as a mirror for the behavior of most adults. As explained in Chapter 29, it suggests that being driven by self-interest is a common human trait, while pursuing a higher, spiritual purpose is a much rarer quality.
