Why was the Tarkhad son hesitant to travel to Shirdi with his mother, and what finally convinced him to make the journey?

The Tarkhad son was hesitant to go to Shirdi because he was deeply devoted to his daily worship of Sai Baba's photograph, which included offering Naivedya before anyone in the house ate. As described in Chapter 9, he worried about who would perform this ritual regularly in his absence, especially since his father was a follower of the Prarthana Samaj and might not engage in idol worship. The son's mind was put at ease only after his father, Babasaheb Tarkhad, gave him a firm assurance. The father promised that he would personally offer the Naivedya to Sai daily and that no one would eat before this offering was made. This solemn promise is what finally convinced the son to undertake the journey to Shirdi.
