Why doesn't the book discuss the lives of other saints, like Saint Francis?

The text doesn't explain why other saints are not mentioned, but it consistently directs the seeker's focus inward toward their own actions and devotion to the Guru. Chapter 19 contains the powerful assurance, 'Those who think of Me with undivided attention... Govinda provides the well-being and security (Yogakshema) of those who are thus constantly united.' This suggests the path lies in this focused devotion, not in comparative study. According to Chapter 19, one should treat Baba's words as authoritative, as they are the 'mine of happiness in this world and the next,' making external validation or information about others secondary to this direct relationship.
