Can you describe the sequence of events that prompted the author's sudden departure for Shirdi?

The author's journey to Shirdi was initiated by an unexpected meeting with an officer named Nanasaheb. Chapter 2 recounts how Nanasaheb questioned the author's procrastination and laziness regarding a visit to Sai Baba. This confrontation made the author feel ashamed but also inspired him due to Nana's pure and loving sincerity. The conversation awakened a strong desire to go, and he gave his word that he would leave immediately. True to his promise, he packed his things, settled his affairs, and departed for Shirdi that very same day at sunset.
