Based on the experiences of Karnik and Appasaheb, what does Chapter 33 reveal about Sai Baba's methods for engaging with his devotees?

Chapter 33 illustrates that Sai Baba engaged with his devotees in varied and sometimes mysterious ways. In the case of Karnik, Baba seemed to operate through another saint, Narsing Maharaj, who forcefully demanded a rupee, creating a powerful experience where Karnik felt Sai himself was accepting it. With Appasaheb, Baba took a more direct, albeit disguised, approach by appearing as a Fakir to claim a promised Dakshina. This served as a test of Appa's faith and resolve, showing that Baba would create pretexts out of love to guide his followers. The chapter concludes that for a devotee of undivided faith, Sai is capable of granting any worldly or spiritual desire, indicating his methods were always aimed at the devotee's ultimate benefit.
