How does the creation and study of a Guru's biography, like the Shri Sai Satcharita, function as a form of service?

The creation and study of a Guru's biography is a dual form of service accepted by the Sadguru. Chapter 0 describes two ways this happens. First, a devotee, like Annasaheb Dabholkar with the Shri Sai Satcharita, performs Guru service by writing the biography. Second, the Sadguru accepts service from the wider congregation of devotees who study and perform Parayans of this work. This collective study is considered a service to 'God in humanity' (Jan-Janardan) and a form of public service. By engaging with a detailed text, both the writer and the readers participate in a sacred exchange that deepens their connection to the Guru and helps the entire community of devotees.
