Once again my memory fails me… I think in the MN (but not sure) there is a sutta which describes an advanced practice where one, just out of will-power and as a practice, turns a pleasant feeling into an unpleasant one, and vice versa.
Does anyone remember which sutta that is?
Excellent, thank you!
I was poking in the MN 120s, but that’s for sure the one I had in mind.
I found the other suttas that contain this teaching, probably it comes from an SN transmission originally: SN 46.54, SN 52.1, SN 54.8, AN 5.144, DN 28.
Perception involves not only feeling, but importantly views:
“Gone astray with wrong views, beings
Mis-perceive with distorted minds.”
"Eventually such thought patterns can become habitual, and evolve into distortions of view (ditthi-vipallasa). We might become so convinced that there is a snake by the path that no amount of evidence to the contrary from our own eyes or reason, nor the advice of others, will shake our beliefs and assumptions. We are stuck in a mistaken view.
Furthermore, these three levels of distortion are cyclical — our perceptions are formed in the context of our views, which are strengthened by our thoughts, and all three work together to build the cognitive systems which make up our unique personality."—Olendzki, translator’s note AN 4.49.
