Based on the incident with Pundalikrao's coconut, how did Sai Baba teach the concept of 'non-doership'?

In the narrative from Chapter 51, Sai Baba uses the incident of the broken coconut to teach Pundalikrao about 'non-doership.' When Pundalikrao felt distressed and considered himself an offender, Baba explained, "You hold onto the idea of being the 'doer' and thus consider yourself an offender. Achieve this state of non-doership, and all troubles will end." Baba emphasized that both the giving and the breaking of the coconut were by His resolve, not Pundalikrao's action. This lesson aimed to free Pundalikrao from the ego-driven pride and guilt associated with his actions, highlighting that a non-egoistic state is the essence of spiritual progress.
