Why was the devotee Sapatnekar so distressed by Sai Baba's behavior towards him, and what did he think was the cause?

Sapatnekar was deeply distressed because while other devotees experienced a "daily Diwali of joy" with Sai Baba, he was consistently met with the rebuke "Chal Hat" (Go away). As described in Chapter 48, this made him feel singled out and question why Baba was angry only with him. He speculated on several reasons for this displeasure, wondering if his past Karma had peaked, if he had violated Dharma and become a shelter for sins, or if it was a consequence of his initial argumentative and doubtful attitude towards Baba when he first came to Shirdi.
