What did Sai Baba's Guru ask for as an offering, and what was the true meaning behind this request?

In a beautiful teaching recounted in Chapter 19, Sai Baba shared a story about his own Guru. After shaving Baba's head, his Guru asked him for two paise. Baba explained that this was not a request for worldly money, as his Guru was a 'Purnakam,' one whose desires were already fulfilled. The true meaning of the two paise was a profound spiritual lesson: they represented the virtues of Faith (Nishtha) and Patience (Saburi). By giving these two metaphorical 'coins,' Baba pleased his Guru and demonstrated the qualities essential for a disciple.
