Can you detail the incident with the eggplants, from the devotee's request to Baba's reaction?

Certainly. The incident, described in Chapter 9, began when a lady devotee gave eggplants to the Purandare family, who were traveling to Shirdi. She lovingly requested that they prepare a mashed dish called 'bharit' and crispy fried slices called 'kachrya' for Sai Baba. Upon their arrival, the family prepared and offered the bharit during the meal after the Arati. Baba tasted it and everyone found it delicious. A moment later, a wish arose in Baba's mind, and he asked for the kachrya. This created a problem, as it was not eggplant season. A search was launched, which led them back to the Purandare family and the story of the lady's offering. As Chapter 9 concludes, this moment made everyone understand the deep love Baba had for the offering and his awareness of the devotee's specific, unspoken wish.
