According to the teachings in Chapter 30, what are the ultimate results of receiving Sai Baba's grace and how is this grace obtained?

Chapter 30 explains that receiving Sai Baba's grace leads to the attainment of "inconceivable great power" and profound spiritual knowledge. The supreme benefit mentioned is gaining the "wealth of discrimination between Self and non-Self," which is a critical form of spiritual wisdom. This grace is obtained by those who have held onto Sai's feet, an act that dissolves all sins. The chapter suggests this is possible because the "dawn of past good impressions (samskaras)" has occurred. It clarifies that this is not due to the devotee's own power but is bestowed by Sai, for whom uplifting His devotees is an unavoidable and essential task.
