Describe the incident where Babasaheb Tarkhad forgot to offer Naivedya and his reaction to it.

One day, Babasaheb Tarkhad, being a chief officer at a large mill, was very busy with his business and forgot to offer the daily Naivedya of sugar candy to Sai Baba's image. Chapter 9 recounts that he only realized his mistake at mealtime when he sat down to eat and the offered 'Prasad' was not served. He was immediately filled with deep remorse and guilt, viewing the oversight not as a simple mistake but a "great sin." He prostrated before Sai’s photograph with tearful eyes, begged for forgiveness, and felt so helpless that he wrote a letter to his son in Shirdi, imploring him to ask Sai for mercy on his behalf.
