Perception as defined in SN 22.79 cannot be really changed:
“And why, bhikkhus, do you call it perception? ‘It perceives,’ bhikkhus, therefore it is called perception. And what does it perceive? It perceives blue, it perceives yellow, it perceives red, it perceives white. ‘It perceives,’ bhikkhus, therefore it is called perception."
But in MN 152 or SN 54.08 vittaka does re-configure perception which is repulsive / un repulsive:
“And how is one a noble one with developed faculties? There is the case where, when seeing a form with the eye, there arises in a monk what is agreeable, what is disagreeable, what is agreeable & disagreeable. If he wants, he remains percipient of loathsomeness in the presence of what is not loathsome. If he wants, he remains percipient of unloathsomeness in the presence of what is loathsome. If he wants, he remains percipient of loathsomeness in the presence of what is not loathsome & what is. If he wants, he remains percipient of unloathsomeness in the presence of what is loathsome & what is not. If he wants — in the presence of what is loathsome & what is not — cutting himself off from both, he remains equanimous, alert, & mindful.”
Is there a definition of perception than covers both?
