What is the significance of performing Parayans of a Guru's biography for both the author and the community?

The text from Chapter 0 explains the dual benefit of performing Parayans of a detailed Guru biography. For the writer, the act of creating the biography is a form of direct Guru service. Concurrently, when other devotees study and perform Parayans of that work, the writer is said to gain the merit of serving God in humanity (Jan-Janardan) and public service. For the other devotees in the community who participate, this devotional study helps them to achieve the purpose of their lives. This creates a powerful spiritual connection between the author, the community, and the Guru.
