How do the stories of Karnik and Appasaheb both illustrate Sai Baba's methods for engaging with his devotees?

Both accounts in Chapter 33 demonstrate how Sai Baba could engage with and test his devotees in unique ways. In Karnik's story, Baba's presence is felt indirectly through another saint, Narsing Maharaj, who forcefully demands a Rupee, making Karnik feel as if Sai himself is accepting it. In Appasaheb's case, Baba's test is more direct, appearing in the guise of an unknown Fakir to see if Appa will fulfill his promise of giving ten Rupees. Both narratives show that divine interaction is not always predictable; it can be a sudden impulse through another person or a direct test of one's integrity, all designed to deepen the devotee's faith and practice.
