How can devotees of Sai Baba engage with his teachings and serve him through literature?

According to the preface of the Shri Sai Satcharita, a Sadguru accepts two forms of service from devotees through books. One way is when the Guru creates a great work themselves, and the other is when they have their biographies written by devotees. As detailed in Chapter 0, devotees can serve Sai Baba by studying and performing Parayans of his biography, the Shri Sai Satcharita. This act of study is considered a form of service to the Guru, and when done by a congregation of devotees, it also serves God in humanity (Jan-Janardan).
