What is the significance of making an offering to Sai Baba, and does he know our inner thoughts about it?

Making an offering is shown to be a significant act of respect. Chapter 35 states, "It is not good to go empty-handed to the door of God, a priest, or a Guru." This prompted Kaka to buy grapes for Baba. The story that unfolds with Boss Dharamsee demonstrates that Baba is acutely aware of our inner thoughts regarding offerings. Dharamsee internally disliked the grapes with seeds that Baba offered him. As this attitude arose, Baba gave him even more. This shows the Guru's deep insight. Ultimately, as detailed in Chapter 35, when Dharamsee obeyed Baba's command to eat, the grapes turned seedless, proving that Baba not only knew his thoughts but also used the offering to dissolve his ego and instill faith.
