What roles did Kaka and Babasaheb Tarkhad play in the story of Dharamsee's visit to Shirdi?

In the story of Dharamsee's transformation found in Chapter 35, Kaka and Babasaheb Tarkhad play crucial supporting roles. Kaka initiated the event by bringing an offering of grapes with seeds, adhering to the principle that one should not visit a Guru empty-handed. These grapes became the medium for the miracle. Babasaheb Tarkhad, another devotee present, served as a vital point of verification. After experiencing the seedless grapes, Dharamsee asked Tarkhad about his own, and Tarkhad confirmed his grapes had seeds. This confirmation highlighted that the miracle was a personal experience for Dharamsee, deepening his astonishment and solidifying his newfound faith.
