What roles did Kaka and Babasaheb Tarkhad play in the incident involving Boss Dharamsee and the grapes?

In the narrative from Chapter 35, both Kaka and Babasaheb Tarkhad played crucial supporting roles. Kaka initiated the event by adhering to the tradition of bringing an offering, purchasing the seeded grapes that Baba would use for his leela. His simple act of devotion provided the physical medium for the miracle. Babasaheb Tarkhad, a fellow devotee, acted as an initial guide for the curious Dharamsee, stating that people come for 'Darshan' and fulfillment of their longings. More importantly, Tarkhad later served as a control subject for Dharamsee's experience. When Dharamsee asked him about his grapes and Tarkhad confirmed they had seeds, it amplified the personal and miraculous nature of Dharamsee's own experience, confirming it was not a general occurrence but a grace meant specifically for him.
