What is a practical way for devotees to build a community and serve the Guru through his teachings?

A practical method for devotees to build a community and serve the Guru is through the study and devotional reading of detailed biographies. As mentioned in Chapter 0, when a devotee performs a Parayan, which is a devotional reading often conducted over a week, of a Guru's biography, they are performing Guru service. When other devotees join in these studies and Parayans, the writer of the work gains merit for serving God in humanity, and the participating devotees also progress in their spiritual lives. This shared practice of studying sacred texts helps foster a strong and dedicated community.
