What was the difference in religious practice between Babasaheb Tarkhad and his son, and how did the father's attitude towards worship evolve?

Initially, there was a significant difference in their religious approaches as outlined in Chapter 9. The son was a practitioner of devotional idol worship, performing daily puja and offering Naivedya to Sai's photograph. In contrast, his father, Babasaheb Tarkhad, was a follower of the Prarthana Samaj, which made the son doubt his father's suitability for such ritualistic worship. However, the father's attitude evolved dramatically. After promising his son, he began performing the worship with sincere prayer, asking Sai to accept his service. His evolution is most evident in his reaction to forgetting the Naivedya; his intense guilt and desperate pleas for forgiveness show that the ritual had transformed from a mere promise into a profound act of personal devotion.
