How was Dharamsee's miracle with the grapes confirmed to be a personal experience and not a general occurrence?

The personal nature of the miracle was a key part of Dharamsee's transformation. As described in Chapter 35, after being amazed to find his grapes were seedless, his ego dropped and love for Sai was born. To confirm what had happened, he approached Babasaheb Tarkhad, another devotee who was also receiving grapes from Baba at the same time. Dharamsee asked him, "How were your grapes?" When Tarkhad replied that his grapes did indeed have seeds, Dharamsee was "extremely surprised in his heart." This confirmed that Baba had not changed all the grapes, but had performed a specific miracle only for Dharamsee, directly addressing his private thoughts and doubts.
