Describe the journey and experience of the devout couple who came to Shirdi to offer khichdi to Sai Baba.

The journey of the devout couple is a beautiful narrative found in Chapter 28 of the Shri Sai Satcharitra. It began when the wife had a vision in Berhampur of Sai Baba asking for khichdi. This sparked their desire for His darshan. After her husband, a Post Department officer, was transferred to Akola, they decided to make the pilgrimage. The text mentions that they saw an auspicious day and set out, worshipping at Gomati tirtha along the way. Upon arriving in Shirdi, they lovingly took Baba's darshan and stayed for two months, joyfully serving at His feet. Their experience culminated in the wife's determined offering of the khichdi, which Baba accepted with great eagerness and delight.
