After realizing he forgot to offer Naivedya, what specific actions did Babasaheb Tarkhad take to show his repentance?

Upon realizing his grave error at mealtime, Babasaheb Tarkhad took several immediate and heartfelt actions to express his repentance. Chapter 9 describes how he was filled with remorse and, at his dining plate, bowed to Sai's image with tearful eyes. He spoke directly to the photograph, calling his forgetfulness a "great sin" and begging for quick forgiveness. He prostrated himself at the feet of the photograph, his heart "choked with grief," and pleaded for compassion. Feeling utterly helpless and believing he had failed his vow, he then sent a letter to his son who was in Shirdi, confessing the "great error" and imploring his son to ask Sai Baba for forgiveness on his behalf.
