What was Sai Baba's relationship with his own Guru like? Can you describe his experience as a disciple?

Sai Baba describes his time with his Guru as a period of profound love and intense devotion. In Chapter 19, he recounts serving his master for twelve years, during which he wanted for nothing in terms of food or clothing, as his Guru's heart was "full of immense love." Baba describes his Guru as a "veritable idol of devotion and love." His own dedication was so complete that he would gaze upon his Guru's face day and night, losing all sense of hunger or thirst. He stated that his mind was restless without his Guru, who was his "only constant contemplation." This deep, unwavering focus was all his Guru expected, and in return, Baba received constant protection and affection.
