What did Sapatnekar think he did wrong to make Sai Baba keep saying 'Chal Hat' to him?

In the narrative from Chapter 48 of the Shri Sai Satcharitra, Sapatnekar was deeply troubled by Sai Baba's constant rebukes. He felt that while everyone else experienced a "daily Diwali of joy," only he received this harsh treatment. He speculated on several reasons for Baba's apparent displeasure. He wondered if his negative karma had reached its peak or if he had violated Dharma and become a "shelter for infinite sins." He also specifically considered that his initial attitude, which had been "argumentative and doubtful about Baba," might be the reason Baba was now putting him in this difficult situation.
