How did Babasaheb Tarkhad's perspective on idol worship appear to shift throughout this story?

Babasaheb Tarkhad's perspective seems to undergo a significant transformation. Initially, he is described in Chapter 9 as a "follower of the Prarthana Samaj," which made his son doubt his willingness to perform idol worship. However, to facilitate his son's journey, he agrees to perform the daily rituals. His commitment grew beyond mere obligation; he prayed earnestly for his service to be accepted. The true shift is revealed when he accidentally forgets the offering. Instead of being indifferent, he is overcome with grief, calling his oversight a "great sin" and feeling immense repentance. This profound emotional reaction indicates that he had moved from a detached observer to a deeply engaged and remorseful devotee.
