Describe what action Babasaheb Tarkhad took to seek forgiveness from Sai after his initial prayers at home.

After prostrating before Sai's photograph and expressing his deep repentance, Babasaheb Tarkhad felt helpless and decided he needed to do more. Chapter 9 explains that he took the step of communicating his failure to his son in Shirdi. Despite the great distance of hundreds of miles, he sent a letter to his son. In this letter, he confessed his transgression, stating, "A great error has occurred through me." He then implored his son to act on his behalf, praying, "ask for forgiveness." This act shows he believed his son, being physically present with Sai, could effectively plead his case and secure compassion for the poor servant who had taken refuge in Baba.
