How did Babasaheb Tarkhad's personal beliefs initially conflict with the devotional practices of his son, and how was it resolved?

The conflict arose from their differing religious inclinations. Chapter 9 states that Babasaheb Tarkhad was a follower of the Prarthana Samaj, a movement that did not typically involve idol worship. In contrast, his son was a devout follower of Sai Baba, whose practice involved the daily worship of a photograph and offering food (Naivedya). This difference created a "great puzzle" for the son when he had to leave for Shirdi, as he didn't know who could properly continue the ritual. The conflict was resolved when the son requested his father to uphold the practice, and Babasaheb, out of love for his son, gave his word that he would personally perform the daily worship and Naivedya offering.
