How does the incident with the grapes demonstrate Sai Baba's method of addressing a devotee's ego and doubt?

The incident with Boss Dharamsee and the grapes, described in Chapter 35, serves as a powerful case study of Sai Baba's teaching method. Rather than offering a sermon, Baba engaged directly with Dharamsee's unspoken thoughts, preferences, and doubts. Knowing Dharamsee's dislike for seeded grapes and his skeptical mindset, Baba deliberately gave him those very grapes, forcing the internal conflict to a crisis point. By commanding him to eat and then transforming the grapes into seedless ones within his mouth, Baba bypassed intellectual argument entirely. This deeply personal miracle demonstrated his omniscience and power in a way that shattered Dharamsee's "clinical scrutiny" and ego, proving that whatever Sai gives, even if initially unappealing, turns out to be beneficial.
