How does the story of Dharamsee and the grapes show Baba's method for dealing with doubt?

This incident provides a powerful example of how Sai Baba addressed a person's doubt not with words, but with direct, personal experience. Instead of simply reassuring Dharamsee, Baba amplified the source of his doubt by giving him more of the very grapes he disliked. As described in Chapter 35, this action was a prelude to a miracle tailored specifically for him. When Baba commanded him to eat and the grapes turned seedless, it shattered Dharamsee's "clinical scrutiny" and ego. The experience was so profound that his doubt vanished and was replaced by love and a "firm determination" to return to Shirdi. This shows Baba's method of transforming skepticism by providing irrefutable, personal proof that addressed the devotee's innermost thoughts.
