What does the term 'Shraddha' refer to in the story of Bhagwantrao Kshirsagar?

In the context of the story about Bhagwantrao Kshirsagar found in Chapter 4, the term 'Shraddha' specifically refers to a death anniversary ritual. The text clarifies this by stating that after Bhagwantrao's father passed away, 'the worship and food offerings ceased, and even the Shraddha (death anniversary) was skipped.' Sai Baba later chided Bhagwantrao for this neglect, indicating that he had failed in his duty to honor his late father. Baba connected this failure to a broader neglect of spiritual duties, noting that Bhagwantrao also kept the family's idol of Vitthal hungry by not offering food (Naivedya).
