Why was Sapatnekar so upset with Sai Baba, and what did he decide to do about it?

Sapatnekar was deeply distressed because every time he went for Sai Baba's Darshan and bowed, Baba would rebuke him with the words "Chal Hat." As described in Chapter 48, he felt singled out, wondering about his past deeds and why Baba, who was loving with others, was so displeased only with him. He even speculated that his initial argumentative and doubtful attitude towards Baba might be the cause. Despite his sorrow and feeling that a 'daily Diwali of joy' was for everyone but him, Sapatnekar made a firm personal determination to stay right there in Shirdi with a steady mind until he received Baba's grace.
