Hi Akvan,
I recalled there was an arrogant Nigantha who challenged the Buddha to a debate. The Buddha taught that the 5 khandhas are annica whereas the Nigantha said otherwise. The Buddha further elaborated His point by asking the Nigantha whether the great kings have sovereign control over the lives of their country folks. The Nigantha said yes. Then, the Buddha returned back to questioning the Nigantha whether he has any sovereign control over his 5 khandhas. The Nigantha went silent and defeated. In the end, he had no choice but to admit that he was wrong. Otherwise, by remaining silent he would risk splitting his head into 7 pieces.
I agree with you that it is worthless and meaningless to cling on to the view that we are in control of everything, especially something like the 5 khandhas which are so close and personal to us, which often trick us into believing that they defined our self with it’s illusory and enigmatic nature. But on the other hand, we also cannot say the 5 khandhas are not ours. Thoughts, views, feelings…etc are clearly residing within our own domain and not in another person.
