Can you recount the story introduced in Chapter 40 concerning Balasaheb Dev and the Udyapan ceremony?

Chapter 40 introduces a narrative about a devout follower of Sai named Balasaheb Dev, who was the Mamlatdar of Dahanu. His mother was deeply religious and had performed numerous vows and fasts. To gain the full merit of these vows, a concluding ceremony known as an Udyapan was required, which involved feeding a large number of Brahmins. As detailed in this chapter, Balasaheb fixed a date for this significant event and wrote a letter to Sakharam Hari Jog in Shirdi. In the letter, he earnestly requested Jog to implore Sai Baba to attend the ceremony, emphasizing that the Udyapan would be incomplete without Baba's divine presence.
