How did Sai Baba's greeting affect the skeptical friend of Kaka Mahajani upon his arrival at the mosque?

Upon arriving at the mosque in Shirdi, Kaka Mahajani's friend had a profound and unexpected experience. Chapter 35 recounts that as the friend set foot on the step, Sai Baba saw him from a distance and called out, "Why have you come in this manner?" The immediate effect was astonishment, as the friend recognized the tone of voice as a perfect imitation of his own deceased father's vocal style. This miraculous event completely disarmed him, causing him to be amazed and to feel as if he were hearing his father speak again, which made him melt inside.
