Describe the complete transformation in Sapatnekar's emotional state, from his initial despair to his final interaction with Baba in this account.

Sapatnekar's emotional journey in Chapter 48 is a dramatic arc from despair to pure joy. He arrived feeling distressed and singled out by Baba's constant rebukes of "Chal Hat," causing him to lose sleep and appetite. However, after resolving to persevere, he had a profound experience. He witnessed Baba narrate his entire life story, which filled him with wonder. This culminated in a deeply moving interaction where Baba acknowledged his grief, promised him a son, and placed a reassuring hand on his head. Hearing Baba’s sweet words, Sapatnekar’s worry vanished, the eight-fold emotions welled up within him, and he was so overcome with tears of joy that he lovingly washed Baba's feet with them.
