How does the text distinguish the practice of writing a Sadguru's biography from other literary services, and what is the ultimate aim of this specific practice?

The text draws a clear distinction based on the spiritual outcome and the nature of the service. As explained in Chapter 0, writing about worldly figures is a worldly service with temporary benefits, while writing about many saints is a partial spiritual service. In contrast, writing the biography of one's Sadguru is presented as the most certain path to salvation. The ultimate aim is not merely the act of writing but the subsequent devotional engagement with the text. This involves performing Parayans and Saptahs with unwavering devotion, which is considered the best form of Guru service for attaining the ultimate spiritual goal.
