I heard a story about Sai Baba and a devotee who brought him khichdi. Can you explain the full story and its significance?

This wonderful story is found in Chapter 28. A devout lady in Berhampur, who had never met Sai Baba, had a dream in which he came to her door and asked for khichdi. This inspired her and her husband to travel to Shirdi. After arriving, they stayed for two months, but for fourteen days, her vow to offer khichdi remained unfulfilled. On the fifteenth day, driven by an intense urge, she went to the masjid during Baba's mealtime. Not heeding the curtain that separated the dining area, she pushed it aside and entered. Baba, seeing the khichdi, became delighted, held the plate with both hands, and eagerly ate it, demonstrating how He fulfills the pure desires of His devotees and honors their devotion.
