What is the proper etiquette when visiting a Guru, according to the events in Shirdi?

The Satcharitra provides guidance on this through a practical example in Chapter 35. It is mentioned that it is considered improper to go 'empty-handed to the door of God, a priest, or a Guru.' Following this principle, a devotee named Kaka, on his way to see Sai Baba, made sure to purchase an offering. He bought two seers of grapes to present to Baba. This act demonstrates the importance of approaching a spiritual master with a token of love, respect, and reverence, signifying that the devotee is not just there to receive but also to offer something from the heart.
