How did Sai Baba get Kaka Mahajani's friend to bow down even though he swore he wouldn't?

The friend of Kaka Mahajani had resolved not to bow to Sai Baba. However, the moment he stepped into the mosque, Baba's actions completely changed his mind. As Chapter 35 recounts, Baba looked at the friend and spoke in sweet words, asking, "Why have you come in this manner?" The tone and vocal style Baba used were a perfect imitation of the friend's deceased father. Hearing this charming tone, which he recognized as his father's exact way of speaking, the friend was amazed and "melted inside." He completely forgot his previous resolve and spontaneously bowed his head at Baba's feet.
