How does the act of studying a Guru's life story, like that of Sai Baba, contribute to one's spiritual path?

Based on the preface in Chapter 0, studying a detailed poetic Guru biography is a form of devotional service. When devotees study and perform Parayans of a work like the Shri Sai Satcharita, they are not just reading a book; they are engaging in a practice through which the Sadguru accepts their service. The text states that by participating in this study, devotees can 'achieve the purpose of their lives.' This devotional engagement with the Guru's biography, facilitated by the writer, creates a virtuous cycle of service and spiritual fulfillment for the entire community.
