I know the question may seems a little trivial and superfluous, but rather than being interested in the itching itself, I'd like to know what to do when any kind of unpleasent feeling rises.
I think itching is different from other unpleasent feelings, mainly because one can easily get rid of that feeling -at least temporarily- by scratching the zone (I mean, to scratch is an option when you have the means).
What would an arahant do when itch arises? What do the suttas tell us to do in situations similar to this one? What do you do when itch arises (apart from recognizing the itch as not-self and impermanent, and the scratching as unsatisfying in the long term and impermanent as a solution)? Or am I overthinking the situation, and should I be aware of the feeling, seeing the three characteristic in it, and just scratch?
I ask this because I remember reading some blog entry about a meditation retreat. The blogger wrote that when meditating, itching was a common feeling, but the hosts told her to let go of the craving for scratching and to not get personally identified with the itch. I understand these instructions and they seem totally reasonable. But she didn't tell about instructions in between meditation sessions other than following the five precepts. Basically, she didn't tell if she was supposed to not scratch even after sitting meditation.
I hope you can see the point in my question, because it seems a little dumb in the surface.
Thanks for your time! Have a nice day!
