From the perspective of an author, what are the multifaceted rewards of writing and publishing a detailed Guru biography?

Writing a detailed poetic Guru biography offers dual benefits to the author. Firstly, the act of writing itself is a form of Guru service. Secondly, when other devotees study and perform Parayans of the completed work, the writer accrues additional merit. As Chapter 0 describes, the author gains the virtue of serving God in humanity (Jan-Janardan) and performing a public service, all while the readers also progress toward achieving the purpose of their own lives through their devotional study.
