How does the process of writing and studying a Guru's biography benefit both the author and the broader community of devotees?

Engaging with a detailed Guru biography offers multiple spiritual benefits. For the writer, the act of creating the biography is itself considered a form of Guru service. Furthermore, as Chapter 0 explains, when other devotees study this work and perform Parayans, the writer accrues the additional merit of serving God in humanity (Jan-Janardan) and performing public service. For the other devotees who study the work, it is a means by which they can achieve the purpose of their lives, creating a virtuous cycle of service and spiritual growth centered on the Sadguru's life.
