What does the source material say about Sai Baba's power and how he interacts with his devotees?

The source material from Chapter 36 portrays Sai Baba as possessing immense power and infinite glory. It is stated that with the mere 'play of his eyebrows,' he can transform a beggar into a king in an instant. For devotees who grasp him through meditation or sing loving hymns to him, he ensures they never lack anything and provides complete protection. On whomever he bestows his grace, he reveals various forms and creates many inconceivable events. The chapter also notes that Sai loves his own stories and uses them as a pretext to fulfill the desires of his devotees.
