Common Faces

There are pretty clear points in common amount mindmapping, martial arts, meditation and so forth. Amount these common points, it would be the ability to link floating concepts, to generate new-coming ideas, free concept associations, concepts and images associations...
Where does this common root resides on?
In my opinion by using the right part of the brain.
As demonstrated, this part of the brain works much better when the arterial tension goes down. Martial arts and also meditation techniques do use the breath to control mental states.
By using these techniques one person can take down the arterial tension and as, a consecuence, induces activity from the right part.
Obviously, in these techniques the whens and the hows are very differents.
