I feel like Baba is angry with me. Sapatnekar felt the same way, right? What was going through his mind?

Yes, Sapatnekar experienced profound distress, believing Sai Baba was angry only with him. As Chapter 48 narrates, while other devotees experienced a "daily Diwali of joy," Sapatnekar was consistently met with the words "Chal Hat." He spiraled into self-doubt, questioning his past deeds and karma. He lamented, "Perhaps my Karma has reached its peak; I have violated Dharma and become a shelter for infinite sins." He even considered that his initial argumentative and doubtful attitude towards Baba might be the cause of this displeasure. This inner turmoil left him sleepless and without an appetite, completely consumed by his perceived separation from Baba's grace.
