How does Chapter 28 describe the ways Sai Baba interacts with his devotees to foster devotion?

Chapter 28 of the Shri Sai Satcharitra explains that Sai Baba connects with his devotees in various profound ways, often appearing to them in dreams to give them darshan. In these dreams, he might give specific instructions, like telling someone to "Remove the trishul," or ask for offerings such as khichdi. The chapter also reveals that he would sometimes discipline his followers, even beating their backs with a stick, or help them break addictions to substances like liquor. According to the text, the ultimate purpose of these diverse interactions, which serve to remove the many troubles of devotees, is to create a deep and abiding love for His own feet.
