How does the text compare the spiritual outcomes of writing about worldly figures versus writing about one's Sadguru, and why are poetic biographies preferred?

Chapter 0 draws a clear distinction between the outcomes of different biographical works. Writing about worldly figures is a service, but its importance and fruit are not eternal, being limited by space, time, and self-interest, thus yielding no spiritual fruit. In contrast, writing the biography of one's Sadguru and engaging with it through devotional reading is described as the most certain service for attaining salvation. Regarding the format, Chapter 0 states that detailed poetic biographies are most suitable for spiritual practices like Parayans and Saptahs. The reason provided is practical: poetry is memorized more quickly and easily than prose, ensuring the teachings stay in the devotee's memory and can be recalled when needed.
