How does the act of studying sacred texts like the Shri Sai Satcharita contribute to both personal growth and community service?

According to the preface, studying a detailed Guru biography is a profound form of service that benefits both the individual and the wider community. Chapter 0 describes this as a way a Sadguru accepts service from devotees. When an individual studies or performs a Parayan, they are performing Guru service. Simultaneously, this act creates a ripple effect. As Chapter 0 details, when other devotees also engage in these studies, the original writer gains the merit of serving "God in humanity" (Jan-Janardan) and public service. This shared spiritual activity helps all participating devotees achieve the purpose of their lives, thereby strengthening the community bond through a common devotional focus.
