What was the role of Babasaheb Tarkhad in the incident with Dharamsee and the grapes?

Babasaheb Tarkhad served as an important point of comparison and confirmation in the story. According to Chapter 35, when Dharamsee, driven by curiosity, first asked Tarkhad why he came to Shirdi, Tarkhad simply replied, 'For Darshan.' Later, after Dharamsee experienced the miracle of the seedless grapes, he asked Tarkhad about the grapes he had received from Baba. Tarkhad confirmed that his own grapes did have seeds. This confirmation was crucial, as it made Dharamsee 'extremely surprised in his heart' and proved that the miracle was a personal one meant specifically for him, reinforcing Baba's omniscience.
