What does the term 'Shraddha' mean in the context of the stories of Sai Baba's devotees, and can you provide an example?

In the context provided in Chapter 35, 'Shraddha' refers to an anniversary ceremony for a deceased person, specifically for the devotee Balaji Patil Nevasakar. This ceremony involved preparing a feast for guests. A notable story describes how during Balaji's Shraddha, the number of guests unexpectedly tripled, causing his wife to worry about a food shortage. However, Balaji's mother-in-law, who had immense faith, declared, "Our Sai is powerful and firm; While he is there, why worry?" She then placed a handful of Udi in each food pot, trusting in Sai Baba to resolve the situation, showcasing how faith was intertwined with such rituals.
