Based on his own experience, what does Sai Baba say a Guru truly wants from a disciple?

Drawing from his twelve years of service to his own master, Sai Baba reveals that a Guru's expectations are not material. As he explains in Chapter 19, his Guru's request for money was purely symbolic. What a Guru truly desires is the disciple's inner cultivation. Sai Baba specifies this as 'strong faith at the Guru’s feet and the strength of courage which is patience.' Furthermore, he describes his own complete absorption in his Guru, stating, 'I would gaze at my Guru's face with love day and night; I felt neither hunger nor thirst.' He concludes that this constant, loving contemplation was all his Guru expected, as his master desired nothing more than this profound devotion and focus.
