What role did the Purandare family play in the story about the eggplants for Sai Baba?

Raghuvir Bhaskar Purandare's family acted as messengers and intermediaries in a story highlighting Sai Baba's connection with his devotees. As detailed in Chapter 9, a lady devotee from Bandra entrusted them with eggplants as they set out for Shirdi. Her specific request was for them to prepare a mashed dish ('bharit') and fried slices ('kachrya') for Baba. The family fulfilled part of the request by bringing the bharit, which was offered after the Arati. Their involvement became crucial when Baba later specifically asked for the kachrya, prompting a search that ultimately revealed the source of the eggplants and the loving intention of the lady who sent them.
