According to the text, what is the role of Sai's grace and his life story in the process of attaining salvation from worldly suffering?

Chapter 17 highlights that achieving one's own salvation from the 'ocean of existence' and its torments requires being endowed with Sai's grace. A practical method to receive this is to approach his life story with respect, through both listening and contemplation. The chapter suggests that by listening to the life story of Shri Sai Nath, individuals and their families can achieve welfare in this world and the next. It is the fortunate and faithful listeners, hearing these wonderful deeds with a gentle heart, who will ultimately find peace.
