the conditions for wisdom to arise are hearing and considering Saddhamma.
On the other hand some people think that some technique is one of the conditions. There are many such techniques and they vary: the mahasi, u ba khin, sunlun, Dhammakaya and so on, but all take intense efforts, long periods of unremitting focusing and the promise of rapid progress.
Such intense concentration inevitably brings special experiences: some pleasant, some unpleasant - and in some of these techniques the instructors suggest that whatever these 'experiences', provided they have some ultra-normal characteristic, whether fear or rapture, shaking or bliss, heavy or light etc etc as being indicative of progress.
So to find which is right, one has to learn what wisdom really is, and what the real conditions for such wisdom are.
