Can you recount the experience of the Noolkar and Dixit families as described in Chapter 9, particularly how Baba's instructions about their departure played out?

Certainly. In Chapter 9, a specific incident involving the families of Tatyasaheb Noolkar and Bhausaheb Dixit illustrates the importance of following Baba's timing. Sai Baba instructed them to leave the following morning and to eat their meal at Kopargaon before continuing their journey. They made arrangements for the meal, but upon reaching Kopargaon, they found it was not ready. Being anxious about catching their train, they went to the station without eating, only to discover that the train was delayed by an hour and a half, demonstrating that Baba's foresight and instructions were perfect.
