The texts mention that one should not go empty-handed to a Guru. How is this principle illustrated in the story of Kaka and Boss Dharamsee's visit?

The principle of making an offering to a Guru is clearly demonstrated at the beginning of this narrative in Chapter 35. The text explicitly states, "It is not good to go empty-handed to the door of God, a priest, or a Guru." Adhering to this custom, Kaka purchased two seers of grapes to offer to Sai Baba upon their arrival in Shirdi. This act of bringing an offering, even a simple one like grapes with seeds, set the stage for the entire leela that followed. It was these very grapes that Baba used as a divine instrument to test and ultimately transform the skeptical Boss Dharamsee. The offering was not just a formality but became the medium through which Baba revealed his omniscience and showered his grace, turning Dharamsee's doubt into unwavering faith.
