How did Babasaheb Tarkhad react when he realized he had broken his vow to Sai Baba, and what actions did he take to seek forgiveness?

When Babasaheb Tarkhad realized he had forgotten the Naivedya offering and thus broken his vow, his reaction was one of profound distress and repentance. According to Chapter 9, he was filled with remorse at his dining plate. He immediately bowed to Sai's image with tearful eyes, questioning how he could have been made to forget and pleading for forgiveness. He prostrated at the photograph's feet, his heart choked with grief, calling himself shameless and acknowledging his failure as a "great sin." In his desperation, he took the significant step of writing a letter to his son, who was hundreds of miles away in Shirdi, confessing the "great error" and imploring his son to ask Sai Baba for forgiveness and mercy on his behalf.
