Can you describe the mistake Babasaheb Tarkhad made in his daily worship and how he reacted when he realized it?

Babasaheb Tarkhad's daily worship routine involved offering a piece of sugar candy as Naivedya to Sai Baba's image. However, as detailed in Chapter 9, one day his mind was busy with business, and he forgot to make the offering. He realized his mistake during his afternoon meal when he noticed the 'Prasad' (the previously offered sugar candy) was not served by the cook as usual. Upon this realization, Tarkhad was filled with extreme remorse and repentance. He bowed to Sai's image with tearful eyes, calling his oversight a "great sin" and a failure for which he felt shameless, and he immediately begged for forgiveness.
