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

According to chapter 35, Kaka Mahajani's friend, a great devotee of the formless who was averse to idol worship, agreed to visit Shirdi with two conditions: he would not bow his head, nor would he provide any Dakshina. Upon arriving at the mosque, Sai Baba saw him from a distance and spoke in sweet words, asking why he had come. The tone of Baba's voice was a perfect imitation of the friend's deceased father, which astonished him and caused him to melt inside. Forgetting his resolve, he immediately bowed his head at Baba's feet. This entire encounter, as detailed in chapter 35, showcases how Baba addressed the friend's skepticism through a deeply personal and miraculous experience.
