After breaking his vow to Sai, what specific actions did Babasaheb Tarkhad take to express his repentance and seek forgiveness?

Upon realizing he had broken his vow by forgetting the Naivedya offering, Babasaheb Tarkhad's repentance was deep and immediate. The account in Chapter 9 details his actions vividly. He was filled with remorse at his dining plate, bowed to Sai's image with "tearfuleyes," and verbally lamented his mistake, calling it a "great sin." His grief was so intense that his heart was "choked with grief" as he prostrated at the feet of the photograph, pleading for mercy. Beyond these personal acts of contrition, he felt so helpless that he wrote a letter to his son, who was hundreds of miles away in Shirdi. In the letter, he confessed his "great error" and implored his son to ask for Sai Baba's forgiveness on his behalf, demonstrating his profound regret and his faith in Sai's power to receive the message.
