The text mentions writing biographies of politicians as a form of service. What spiritual benefits does the author say this provides?

The preface in Chapter 0 makes a clear distinction regarding this type of service. It acknowledges that writing biographies of worldly figures like politicians is a form of worldly Guru service, but it explicitly states that this practice does not yield spiritual fruits. The author argues that such service is limited by time and space and is often rooted in self-interest. According to the perspective offered in Chapter 0, true spiritual benefits come from writing the biographies of saints, and most profoundly, from writing the biography of one's own Sadguru.
