What does the story about Kaka buying grapes teach us about approaching a Guru?

The brief mention of Kaka in Chapter 35 offers a simple yet important lesson on the proper attitude when approaching a spiritual master. The text explicitly states, "It is not good to go empty-handed to the door of God, a priest, or a Guru." Following this principle, Kaka thoughtfully bought two seers of grapes to offer to Sai Baba before his Darshan. Even though his preferred seedless variety wasn't available, he bought what was available, demonstrating that the act of giving and the sincerity of the offering are more important than the material perfection of the gift itself. This act, as described in Chapter 35, sets the stage for the subsequent miracle and illustrates the devotee's role in creating an opportunity for grace through a humble, respectful offering.
