Can you describe the relationship Sai Baba had with his own Guru based on his account in Chapter 19?

In Chapter 19, Sai Baba portrays his relationship with his Guru as one of profound love, devotion, and complete absorption. He recounts staying at his Guru's feet for twelve years, during which he was raised with immense love and never lacked for food or clothing. He describes his Guru as a "veritable idol of devotion and love." Their bond was so deep that Baba's primary spiritual practice was simply gazing at his Guru's face, which would send his eyes into meditation. He states, "I would gaze at my Guru's face with love day and night; I felt neither hunger nor thirst; without the Guru, my mind was restless." This constant contemplation was all his Guru expected, and in return, the Guru always protected him.
