In the story of Bhagwantrao Kshirsagar, what is the 'Shraddha' that he neglected and why was it important?

In the context provided by Chapter 4, the 'Shraddha' that Bhagwantrao Kshirsagar neglected refers to the death anniversary ceremony for his late father. This was a significant lapse in his duties. After his father, who was a great devotee of Vitthal, passed away, Bhagwantrao not only stopped the daily worship and food offerings to the family's Vitthal idol but also skipped this important annual rite. Sai Baba, who referred to the father as his friend, highlighted this neglect as a serious issue. By ceasing the Shraddha, Bhagwantrao was failing to honor his ancestor's memory and spiritual path. Baba's intervention was crucial to remind him of this responsibility and put him back on the path of worship and remembrance.
