Can you describe the incident where a skeptic's mind was changed by the sound of Sai Baba's voice?

Chapter 35 recounts a powerful incident involving a friend of Kaka Mahajani who was a firm believer in the formless and was against idol worship. He went to Shirdi with the firm condition that he would not bow or give money. Upon setting foot in the mosque, Sai Baba saw him from a distance and called out in sweet words. The specific tone and manner of Baba's speech were an exact imitation of the friend's deceased father's voice. This uncanny resemblance astonished the man, causing him to melt inside and completely forget his prior resolutions. He immediately bowed his head at Baba's feet, demonstrating the profound and transformative power that was contained even in the sound of Baba's speech.
