Can you summarize the transformation of Kaka Mahajani's friend during his first visit to Shirdi?

The journey of Kaka Mahajani's friend to Shirdi, as narrated in Chapter 35, is a powerful story of transformation from skepticism to devotion. He began as a devotee of the formless, averse to idol worship, and agreed to go only out of "clinical curiosity," setting firm conditions that he would not bow his head nor offer Dakshina. However, upon arriving at the mosque, Sai Baba spoke to him in a voice that uncannily resembled his deceased father's. This deeply moving experience caused him to forget his resolve and bow at Baba's feet. Later, when Baba twice requested Dakshina from Kaka but pointedly ignored the friend, the friend, who had vowed not to give, became restless. This series of events shows how Baba worked on his consciousness, breaking down his intellectual barriers and stirring his heart without direct confrontation.
