How does Shri Sai Baba portray his personal relationship with his Guru in Chapter 19, and what did his Guru desire most from him?

In Chapter 19, Shri Sai vividly illustrates the ideal Guru-disciple relationship through his own experience. He recounts serving his Guru for twelve years, during which his master provided for all his needs with immense love. Sai's devotion was absolute and all-consuming; as he states, 'I would gaze at my Guru's face with love day and night; I felt neither hunger nor thirst.' His Guru was his only meditation and goal. Crucially, Chapter 19 reveals that this intense, unwavering focus was precisely what his Guru desired. The text notes that the Guru expected nothing more than this constant, loving contemplation from his disciple, and in return, he always offered protection and care.
