How can devotees serve Sai Baba and help others connect with his teachings through written works?

Based on the preface in Chapter 0, a Sadguru accepts service from devotees through books in two primary ways. One significant method is by having his biographies written by his devotees. By studying and performing Parayans (devotional readings) of a detailed biography like the Shri Sai Satcharita, the writer performs Guru service. Furthermore, as other devotees also study and perform these Parayans, the writer gains the merit of serving God in humanity, and those other devotees can achieve the purpose of their lives. This creates a powerful community of study and devotion centered on the Guru's life.
