However, I question whether there's actually a shared context when it comes to meditation. Unlike for external phenomena like gravity and QM, there's a lot of ambiguity related to communicating internal processes. For example, basic emotions like happiness and fear are easily communicated because they show up on the face. Two people can agree that the emotion that causes them to make the same face is the same one, and so can agree to call the emotion by a word. But are we sure the same is true for things that don't work like this? If someone says "do this and you'll feel like that" and I do and I don't feel that, what am I to understand? Is it that I did it wrong, that I did it right and my brain just works differently, or that the speaker and I are failing to understand each other? Did the speaker misuse a word? Did I mistakenly think a word meant something other than what was intended? Particularly when it comes to subjective feelings there's going to be a lot of metaphors involved, which never help for unambiguous communication.
