What is the significance of bringing an offering when one goes for a Guru's darshan, based on the texts?

The texts suggest it is a virtuous practice to not approach a Guru, God, or priest empty-handed. Chapter 35 provides a clear example of this principle in action. A devotee named Kaka, on his way to Shirdi, remembered this and bought two seers of grapes to present to Sai Baba. This offering, though simple, became the very instrument through which Baba performed a profound leela. Baba used these grapes to teach a lesson and transform the heart of a skeptical visitor, Boss Dharamsee. This illustrates that a humble offering can become a catalyst for receiving the Guru's grace and experiencing a divine lesson.
