Please summarize the incident involving Mrs. Khaparde's food offering and Sai Baba's reaction.

The incident involving Mrs. Khaparde's food offering is a key story from Chapter 27. The lady, who was extremely devout, brought a plate full of various dishes as an offering. As soon as the plate arrived, Baba became very eager, a reaction that was unusual for him. He immediately got up, went to the dining spot, and prepared to eat. When a devotee questioned this apparent partiality, Baba explained his actions by revealing a connection to the lady from her previous lives, stating she was once a cow he knew. He then ate the food heartily, burped with satisfaction, and later offered words of welfare to the lady as she massaged his feet, demonstrating his unique method of bestowing grace through loving and personal interactions.
