The text mentions 'Shraddha' in the story of Bhagwantrao Kshirsagar. What does this term refer to in that specific context?

In the context of Bhagwantrao Kshirsagar's story, 'Shraddha' refers to the death anniversary ritual for his father. According to Chapter 4, after Bhagwantrao's father, who was a great devotee of Vitthal, passed away, the family worship and food offerings ceased. The text explicitly states that 'even the Shraddha (death anniversary) was skipped.' Sai Baba later reminded Bhagwantrao of this neglect, stating that by not performing these duties, he was keeping both Vitthal and Baba hungry. Baba's stated intention was to guide him back to his devotional practices and put him back to worship.
