In his story about his own spiritual training, what does Sai Baba say was the ultimate expectation his Guru had of him?

In the personal account shared in Chapter 19, Sai Baba reveals that what his Guru ultimately expected was not a secret mantra or material offering, but his complete and unwavering devotion. Baba describes how he spent twelve years at his Guru's feet, developing an intense focus. He says, '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.' He concludes that this state of being, where the Guru was his 'only constant contemplation,' was all his master truly desired. This intense devotion was the culmination of the faith and patience his Guru had asked for earlier.
