How does Sai Baba describe his relationship with his Guru and the nature of his devotion?

Chapter 19 provides a moving account of Sai Baba's intense devotion to his Guru. He recounts spending twelve years at his Guru's feet, a period during which his focus was so complete that he felt neither hunger nor thirst. Baba 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 unwavering contemplation was precisely what the Guru desired, expecting nothing more than this profound faith and patience. In return, as described in Chapter 19, the Guru provided immense love, protection, and care, ensuring Baba never lacked for anything.
