I thought this was an interesting question. Monks seem to be doing various activities to condition the mind, things like metta or the Tibetan eight verses of mind training. Even the five precepts and the noble eightfold path could be called forms of conditioning, as they are things you accept and work with.
So can you arrange the mind in such a way through training it that just a little bit of meditation pushes it over the edge and go whoosh, enlightened? And are we ultimately anything more than just conditioning on top of conditioning? There is no self, is the mind just a conditioning machine?
