The texts mention two ways a Sadguru takes service through books. How does this apply to Sai Baba and community development?

Chapter 0 explains that a Sadguru accepts service through books in two primary ways: either by creating great spiritual works themselves, or by having their biographies written by devotees. The community then engages with these biographies through study and Parayans. In the case of Shri Sai Baba, the second method is highlighted. His devotee, Annasaheb Dabholkar, wrote the Shri Sai Satcharita. By studying this work, the community of devotees performs a service to their Guru. This shared practice of studying and performing Parayans of this detailed biography is a foundational activity for fostering a community and allowing devotees to achieve the purpose of their lives.
