What is the significance of the Shraddha ritual in the story of Bhagwantrao Kshirsagar?

In the story of Bhagwantrao Kshirsagar, the Shraddha, or death anniversary ritual, is highlighted as a crucial duty that was being neglected. Chapter 4 recounts that after Bhagwantrao's father, a great devotee of Vitthal, passed away, the family stopped performing the worship, food offerings, and even the Shraddha. When Bhagwantrao came to Shirdi, Sai Baba, who called the father his friend, pointed out this neglect. Baba stated that by skipping these duties, Bhagwantrao was keeping both the family's Vitthal idol and Baba himself hungry. Baba explicitly said he brought Bhagwantrao to Shirdi to remind him of these responsibilities and to "put him back to worship," showing the importance he placed on continuing these ancestral devotional practices.
