How did the devotional paths of Balaram Dhurandhar and his father differ from each other?

Chapter 51 presents a subtle yet clear distinction between the devotional practices of Balaram and his father. While the entire Dhurandhar family was characterized by their firm faith in Shri Rama, the text specifies individual preferences. It explicitly states that the father's chosen deity was Rama, aligning with the family's general inclination. In contrast, it notes that for the son, Balaram, his "refuge was Vithala." This highlights a personal or perhaps generational shift in devotional focus, where Balaram developed a specific and deep connection to Vithala of Pandharpur, even as he was part of a household primarily dedicated to Rama.
