Beyond faith and patience, what did Sai Baba's Guru expect from him, and what was their relationship like?

As detailed in Chapter 19, Sai Baba's Guru desired his disciple's complete and loving contemplation. Sai Baba recounts how he would gaze at his Guru's face day and night, feeling neither hunger nor thirst, and his mind knew no other goal. This constant, loving focus was all the Guru expected. In return, the Guru's heart was full of immense love, and he was a "veritable idol of devotion and love" who never neglected his disciple. He raised Sai Baba from a child to an adult, providing for all his needs and protecting him in times of trouble, creating a relationship of profound mutual joy and devotion.
