How does the act of writing and sharing a Guru's biography create a dual benefit for the author and the community?

The creation of a detailed poetic Guru biography offers a twofold benefit. As explained in Chapter 0, the writer performs a direct and valuable form of Guru service through the act of authorship. Simultaneously, a second benefit arises when other devotees study and perform Parayans of that work. In this case, the writer gains the merit of serving God in humanity (Jan-Janardan) and performing public service. This dynamic allows the Sadguru to take two types of service from devotees through books, thereby helping both the author and the wider community of devotees achieve the purpose of their lives.
