How does the creation and study of a Guru's biography foster a sense of community and shared purpose among devotees?

The preface in Chapter 0 explains that engaging with a Guru's biography is a powerful community-building practice. When a writer creates a detailed poetic biography, they perform Guru service. This service is amplified when other devotees also study and perform Parayans of that same work. This shared act of devotion helps all participants achieve the purpose of their lives. The writer, in turn, gains the merit of serving God in humanity (Jan-Janardan) and performing a public service. This collective study and recitation create a communal focus, uniting devotees in their service to the Sadguru and their shared spiritual journey.
