Can you tell me the story of how Babasaheb Tarkhad forgot his promise and what happened as a result?

Chapter 9 recounts that Babasaheb Tarkhad began performing daily worship, offering a piece of sugar candy as Naivedya to Sai. However, one day, his mind was preoccupied with business, and he forgot to make the offering. Consequently, everyone in the house finished their meals without the Naivedya being offered first. Later, when Tarkhad sat down to eat, he realized his mistake because the cook did not serve him the leftover sugar candy, which he normally consumed as 'Prasad'. This realization filled him with immense remorse and guilt for breaking his vow.
