What is the significance of bringing an offering to a Guru like Sai Baba, as seen in the story of Kaka buying grapes?

Chapter 35 highlights the tradition that 'it is not good to go empty-handed to the door of God, a priest, or a Guru.' This act of bringing an offering, like the grapes Kaka bought, is a gesture of respect and humility. The offering itself becomes a vehicle for the Guru's grace and teachings. In this specific narrative, the grapes—an imperfect offering since they had seeds and the seedless variety was unavailable—became the central element in a profound lesson for the skeptical Boss Dharamsee. Baba used this simple gift to perform a miracle that addressed Dharamsee's specific dislike, demonstrating his omniscience and turning a skeptic into a devotee. This shows that the value is not in the offering itself, but in the devotee's intention and how the Guru chooses to use it for spiritual upliftment, as seen in Chapter 35.
