According to the teachings in Chapter 30, what is the role of a devotee's faith and past impressions (samskaras)?

Chapter 30 explains that the dawn of past good impressions, or samskaras, enables devotees to hold onto Sai's feet, which leads to the dissolution of all sins and makes their path fearless. However, the chapter also offers hope for those who feel they are of little power and lack proper samskaras, stating emphatically that Sai does not forsake them. Sai's grace is described as a powerful force that can bestow inconceivable power and the "wealth of discrimination between Self and non-Self." As detailed in this chapter, devotees who crave Sai's words and trust him completely become fulfilled because Sai Nath is capable of fulfilling their heart's desires.
