Can you explain the story of the eggplant dishes served to Sai Baba and what it reveals?

The story, found in Chapter 9, involves a devotee who sent eggplants with the Purandare family traveling to Shirdi. She requested they prepare 'bharit' (mashed eggplant) and 'kachrya' (fried slices) for Baba. At mealtime in Shirdi, the 'bharit' was served and enjoyed. Immediately, Baba expressed a desire to eat the 'kachrya'. This caused confusion, as it wasn't the season for eggplants and no one knew where to find them. A search led them to the lady who brought the 'bharit', and upon asking her, they learned about the original request to make both dishes. This incident revealed Baba's omniscience and his deep connection to his devotees' unspoken wishes, showing that he knew about the intended but yet-unprepared second dish.
