What is the dual benefit gained from the writing and reading of a detailed Guru biography?

The creation and study of a detailed poetic Guru biography provides a profound dual benefit. For the author, the act of writing the biography is a direct form of Guru service. At the same time, as Chapter 0 describes, when other devotees study this work and perform Parayans, the writer gains the additional merit of serving God within humanity (Jan-Janardan) and performing a public service. This process not only serves the Guru but also helps both the writer and the community of readers to achieve the purpose of their lives through shared devotional engagement with the text.
