How does the act of studying a Guru's biography, like the Shri Sai Satcharita, help a devotee?

According to Chapter 0, studying a detailed poetic Guru biography is a form of Guru service. The Sadguru accepts this service from the congregation of devotees who perform study and Parayans. This engagement is not just a passive reading; it is an act of devotion that helps the devotees achieve the purpose of their lives. By immersing themselves in the inspirational and grace-filled biography of a saint like Shri Sai Baba, as written by Annasaheb Dabholkar and published as the Shri Sai Satcharita, followers can find renewed purpose and overcome feelings of spiritual stagnation. The text itself becomes a conduit for the Guru's grace.
