There's a tradition of not visiting a Guru empty-handed. How is this demonstrated during Boss Dharamsee's first visit to Shirdi?

This principle is clearly illustrated in the narrative from Chapter 35. The text explicitly states, 'It is not good to go empty-handed to the door of God, a priest, or a Guru.' Following this tradition, a devotee named Kaka, who was accompanying Boss Dharamsee, thoughtfully bought two seers of grapes on the way to Shirdi to offer to Baba. These very grapes, though not the seedless variety he sought, became the instrument through which Baba performed a leela for Dharamsee, ultimately transforming his skepticism into deep faith.
