It seems to me that mediation works in many situations, and I suspect that most of the explanatory frameworks that come along with the meditative techniques are far from optimal.
It seems that the greater the level of awareness and context control we can create in the gap between impulse and action (at all levels of awareness), the greater the level of influence we can choose about who we get to be in this reality we find ourselves in (whatever it actually is).
Personally,I find the heuristics of biochemistry, logic, games theory, evolutionary theory, probability, etc far more useful than most of the explanatory frameworks that tend to come with meditation traditions. So I work at keeping clear distinctions between the practices, and the explanatory contexts accompanying them.
And I seem to have taken that general approach to life to levels that few others have – so communication is often difficult.
And I am conscious that all explanatory frameworks are useful models in some sense, and that our brains do not have sufficient capacity to model the complexity of reality without making heuristic assumptions (even in the best models available from science)- so even the best models of science are subject to a vast range of errors if one pushes them too hard, and provided one is conscious of that, then they do appear to provide greater utility in most situations provided one is willing to put in the time to develop a probabilistic context that always has a degree of uncertainty with any prediction (it may be very tiny, and it will be present).
