The book seems to dismiss writing about historical figures like politicians or warriors. Why is this type of biographical work considered inferior to writing about saints?

The text acknowledges that writing biographies of great worldly figures like politicians or warriors is a form of Guru service, but it categorizes this as worldly service. According to the Preface in Chapter 0, this service is "limited by space and time" and, because it is often "rooted in self-interest," it "does not yield spiritual fruits." In contrast, writing the biographies of saints is considered a spiritual endeavor that produces spiritual benefits, and writing about one's own Sadguru is presented as the highest form of this service for attaining salvation.
