Based on Chapter 36, how is the nature of Sai Baba's grace and power described, and how does the story of the Goan visitors serve as an example?

Chapter 36 describes Sai Baba as a saint of infinite greatness and prowess, an incarnation of the knowledge of Truth who can create many inconceivable events. It states that on whomever he bestows his grace, he shows them various forms and never lets them lack anything. The story of the two gentlemen from Goa serves as a direct example of this. Sai's act of asking for fifteen rupees from one man while rejecting thirty-five from another is presented as one of these 'inconceivable events' that demonstrates his unique way of operating. As Chapter 36 explains, he stays 'distant and detached from his name' but 'causes various events to occur,' fulfilling the desires of devotees through his mysterious play, which may not be immediately understood by onlookers.
