How can a devotee perform Guru service through the study of sacred texts, and what are the benefits for the individual and the community?

According to Chapter 0, studying and performing Parayans (devotional readings) of a detailed poetic Guru biography is a direct form of Guru service. When an individual engages in this practice, they are not only serving the Guru but also working towards achieving the purpose of their own life. The benefits extend beyond the individual to the entire community. The text states that when other devotees also study and perform these Parayans, the original writer gains the merit of serving God in humanity (Jan-Janardan) and performing public service, which strengthens the entire congregation of devotees.
