What happened when Kaka Mahajani's friend, who was skeptical of idol worship, first visited Shirdi?

Kaka Mahajani's friend, a devotee of the formless God, was initially averse to idol worship and agreed to visit Shirdi out of clinical curiosity. As described in Chapter 35, he made two conditions: he would not bow his head to the saint, nor would he offer any Dakshina. However, upon arriving at the mosque, Sai Baba saw him and spoke. The tone of Baba's voice was a perfect imitation of the friend's deceased father. This miraculous and personal experience astonished the friend, causing him to melt inside and forget his resolve. He immediately bowed his head at Baba's feet, completely overwhelmed by the encounter.
