Based on Chapter 30, how does a person change after receiving Sai's grace?

As described in Chapter 30, receiving Sai's grace brings about a profound transformation. The text states that when grace is bestowed, the person 'attains inconceivable great power.' This isn't just worldly power, but includes the 'wealth of discrimination between Self and non-Self,' signifying deep spiritual wisdom. Furthermore, the chapter explains that Sai Nath intimately knows the heart's desires of His devotees and is uniquely capable of fulfilling them. This grace leads followers to a state of complete fulfillment, as their deepest needs and aspirations are met by the compassionate saint.
