How does the act of studying a Guru's biography, like the Shri Sai Satcharita, contribute to both individual and community spiritual growth?

The study and performance of Parayans of a detailed Guru biography serves multiple spiritual purposes. According to Chapter 0, for the individual, it is a form of Guru service. For the community, when other devotees also study and perform these readings, the writer gains the merit of serving God in humanity (Jan-Janardan) and public service. This collective participation helps all devotees achieve the purpose of their lives. The text highlights that the Sadguru accepts service from devotees through study and Parayans from both the writer and the congregation of devotees, creating a shared spiritual experience.
