How can devotees serve their Guru and the wider community through literature?

The source material explains that a Sadguru accepts service from devotees through books in two main ways. As detailed in Chapter 0, one way is by having devotees write their biographies. The writer performs Guru service, and when other devotees study and perform Parayans (devotional readings) of these works, the writer gains merit for serving God in humanity. This act of shared study helps other devotees achieve the purpose of their lives, fostering a community of practice and public service.
