The book mentions writing biographies. Is writing about any great person considered a path to spiritual salvation?

The preface makes a clear distinction between different types of biographical writing. According to Chapter 0, writing biographies of great men like unique politicians, state-founding brave warriors, or extraordinary jurists is considered a form of worldly Guru service. While valuable, this service is described as being limited by space and time, rooted in self-interest, and therefore does not yield spiritual fruits. In contrast, writing the biographies of saints is a form of Guru service that does yield spiritual fruits, though it is still considered a partial path to the ultimate goal.
