How can devotees engage in service to Sai Baba and his teachings through literature?

Based on the preface in Chapter 0, a Sadguru accepts service from devotees through books in two primary ways. One method is by having their biographies written by devoted followers. Another way is by accepting service in the form of study and 'Parayans' (devotional readings) from both the writer and the wider congregation of devotees. Therefore, creating, studying, and performing Parayans of detailed poetic biographies about a Guru is a significant form of service. This not only benefits the individual but also serves the broader community, as it allows other devotees to achieve the purpose of their lives.
