How does the process of writing and reading a Guru's biography benefit both the author and the devotee community?

As detailed in Chapter 0, the creation and study of a Guru biography is a multifaceted service with widespread benefits. For the author, the act of writing a detailed poetic biography is considered a direct form of service to their Guru. Simultaneously, by making the work available to others, the writer gains the merit of serving God in humanity (Jan-Janardan). For the community of devotees, studying and performing Parayans of the biography is not just an act of devotion but a means by which they can achieve the purpose of their lives, a form of service the Sadguru graciously accepts from them.
