Great post!

As a reference, some hardcore meditators have tried a more extreme version of this under the name "Actual Freedom" with the goal of essentially eliminating all affect and ending suffering in that way. The name comes from this site, which originated the approach, but it's, well, a bit on the nutty side of the sanity spectrum. (I mean, just look at it.) Better information is available on the Dharma Overground, a meditation site run by Daniel Ingram who's been mentioned already a couple of times here.

As far as I understand Actual Freedom, the idea is basically to trace exactly moment-to-moment the emotional changes one is going through. That way, one can perceive exactly when emotions arise and they can be directly attended to and stopped.

I'm not endorsing this, but I thought that a more extreme view of this kind of method might be interesting. I'm mostly distancing myself because, even though some people seem to have achieved good results (e.g. Tarin Greco), almost all of them seem like nutjobs to me, but maybe they are really happy nutjobs. Also, they haven't yet managed to provide clear, comprehensive descriptions of what they are actually doing and attempts of doing in-depth discussions have so far led to a lot of internet drama.
