What is the significance of the khichdi offering in the story of the devout couple from Akola?

The khichdi offering is central to the story of the devout couple, symbolizing the fulfillment of a spiritual call. The entire journey began when the lady, then in Berhampur, had a vision of Sai Baba asking for khichdi. As detailed in Chapter 28, this prompted the couple to travel to Shirdi from Akola with the specific vow to offer khichdi naivedya. After arriving, they faced a delay of fourteen days, unable to make the offering. The lady's determination grew so strong that on the fifteenth day, she boldly pushed past the curtain where Baba was eating and entered to fulfill her desire, showing the immense importance she placed on completing the vow that Baba himself had initiated in her dream.
