According to the author, what is the most effective way to serve a Guru through writing?

The author posits that the best and most certain form of literary service that leads to salvation is to write the biography of one's own Sadguru. As detailed in Chapter 0, this act should ideally be undertaken by the Guru's command or through a strong inner inspiration. It is not merely about the writing itself, but also about the spirit in which it is done—with a pure heart, excellent faith, selfless love, and unwavering devotion. The service is completed by personally studying the work, performing regular readings (Parayans) and weekly recitations (Saptahs), and encouraging others to do the same. This form of service is considered superior to writing about worldly figures or even multiple saints.
