What promise did Babasaheb Tarkhad make regarding the daily Naivedya, and what were the consequences when he forgot?

Babasaheb Tarkhad made a solemn promise to his son that he would personally continue the daily worship of Sai Baba's photograph and, crucially, that no one in the household would eat their food until the 'Naivedya' had been offered. Chapter 9 explains that he followed this routine by offering a piece of sugar candy daily. However, one day, being preoccupied with his business, he forgot to make the offering. The consequence was that the entire family finished their meals without the food first being dedicated to Sai. When Babasaheb sat down to eat, he realized his mistake because the cook didn't serve him the usual 'Prasad'. He was immediately filled with immense remorse and guilt, considering the oversight to be a great sin.
