What are some established methods for devotees to collectively engage with a Sadguru's teachings and foster a sense of community?

The source material suggests that a key way to build a community and serve a Sadguru is through the study of their biographies. As detailed in Chapter 0, the Sadguru accepts service from devotees through books in two primary ways. Devotees can either engage with great works written by the Sadguru himself or, more relevant to community building, they can study and perform Parayans, or devotional readings, of biographies written by other devotees. By studying and performing these Parayans, both the writer and the congregation of devotees can achieve the purpose of their lives and gain merit. This collective study forms a powerful basis for a community centered around the Guru's life and teachings.
