Describe the specific reasons the devotees felt regret and repentance after Baba left his physical form.

The devotees experienced deep repentance because they felt personally responsible for Sai Baba's departure. Chapter 43 reveals their belief that their "petty vision" and internal conflicts caused him pain. They specifically recalled Baba's teaching, "It is not good to harass anyone; that gives me pain," and realized they had failed to heed his words. They felt that by "harassing devotee after devotee," they had effectively driven him away and "lost Sainath." This self-blame and the memory of their own fighting was the primary source of their sorrow and repentance, feeling that the compassionate friend who was once so close had become a stranger due to their actions.
