After realizing he had forgotten the Naivedya offering, what steps did Babasaheb Tarkhad take to seek forgiveness?

Upon realizing his mistake of forgetting the Naivedya, Babasaheb Tarkhad was filled with immense grief and took immediate steps to seek atonement. The narrative in Chapter 9 explains that his first act was to prostrate at the feet of Sai Baba's photograph, confessing his failure with a heart choked with grief and tearfully begging for mercy. Feeling utterly helpless, he then took the further step of writing a letter to his son, who was in Shirdi. In the letter, he confessed the "great error" and implored his son to ask for forgiveness directly from Sai Baba on his behalf.
