Did Kaka Mahajani's friend adhere to his resolution not to bow to Sai Baba? Explain what transpired.

No, he did not adhere to his original resolution. Despite his firm decision to not bow his head, the friend's resolve was completely forgotten after his initial interaction with Sai Baba. According to the account in Chapter 35, hearing Baba speak in the exact voice of his late father had a powerful emotional impact on him. The text states that the friend "melted inside" upon hearing the familiar speech. In that moment, he completely forgot his prior resolve and spontaneously bowed his head at Sai Baba's feet, a direct contradiction of the conditions he had set before the visit.
