I've heard about Sai Baba's miracles. Can you give me an example from the scriptures of how he used his power and for what purpose?

Chapter 35 recounts a fascinating incident involving a devotee named Kaka, who brought grapes with seeds as an offering. A visitor, Boss Dharamsee, who disliked seeded grapes, was present. When Baba offered him these grapes, Dharamsee was troubled and even questioned Baba's sainthood internally. However, when Baba insisted he eat them, Dharamsee discovered they had become seedless. This amazed him, and he thought, "What a strange power! What is impossible for these saints?" The purpose of this miracle was not mere showmanship; it was to address Dharamsee's specific doubt and ego. As the text states, his "ego dropped away, and love for the saint was born." This shows Baba used his powers to inspire devotion and lead individuals onto the spiritual path.
