Vedanā (pronounced VAY-dunna) is Pāli for raw physical sensation, which can be objectively observed in meditation to provide insight into the impermanent nature of all things.
I think this is my favorite episode of American Masters series to date. That's an excellent clip... it makes me want to see the whole episode again. If you haven't already, I hope you get a chance to see it in its entirety. Very special, indeed. Thanks for the clip. Namaste
