What do the scriptures say about the proper etiquette when visiting a Guru, and how is this demonstrated in the story from Chapter 35?

Chapter 35 provides a clear principle regarding visiting a spiritual master, stating, 'It is not good to go empty-handed to the door of God, a priest, or a Guru.' This teaching is immediately put into practice by the devotee Kaka. On his way to Shirdi for Baba's darshan, Kaka bought two seers of grapes to present as an offering. The text notes that while his preferred seedless variety wasn't available, he purchased the seeded ones that were. This act of devotion and adherence to proper conduct is what set the stage for the subsequent miracle involving Boss Dharamsee, demonstrating the importance of making a humble offering when approaching a Guru.
