What was Sai Baba's explanation to Pundalikrao regarding the coconut incident, and what was the ultimate lesson?

Sai Baba explained to Pundalikrao that he should not be distressed about the broken coconut. As detailed in Chapter 51, Baba revealed that it was His own resolve that the coconut was given and that it subsequently broke. He taught Pundalikrao about the importance of achieving a state of "non-doership" to end all troubles and let go of the pride of being the 'doer'. The core lesson, as stated in the text, is that the more non-egoistic one's state, the more authority one gains on the spiritual path, making it easier to overcome life's challenges.
