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

The narrative in Chapter 35 provides a simple yet profound lesson on approaching a Guru. It explicitly states, 'It is not good to go empty-handed to the door of God, a priest, or a Guru.' Following this principle, Kaka bought two seers of grapes on his way to Shirdi to offer to Sai Baba. He didn't find the seedless variety but bought what was available, demonstrating that the sincerity of the offering is more important than its perfection. This act of bringing an offering, no matter how simple, is a mark of respect and devotion when seeking the presence and blessings of a spiritual master.
