Can you tell me the story about the devout lady who brought khichdi for Sai Baba?

Certainly. Chapter 28 recounts the wonderful story of a devout lady from Berhampur. She had never met Sai Baba in person but had a powerful dream in which he came to her door and asked for khichdi. This vision deeply moved her and her husband. After his work transferred him to Akola, they journeyed to Shirdi. They stayed for two months, but for fourteen days, she was unable to make her offering. Finally, on the fifteenth day, her determination was so strong that she pushed aside the curtain while Baba was eating and fulfilled her vow, demonstrating the power of heartfelt devotion.
