I consider nothing is "all in the mind" which is all in the body.
Plainly we are born(e) into thought of thought. We are our creation in the physical world of an internal world. External occurences are taken as directly a consequence of our thoughts.
There are consequences when we believe the converse, outside in. We can only arrange them as fictions, and will resort to fiction as tool as a result.
This does begin as exercise of being in young adulthood, which must be the epicentre sought in analysis, not early "memory". We are seeking where language is known as destructured. For this is what thought was and all that memory between the epicentre and source movement is. Nothing will be other than a sample from that depth. We seek the surface of the present shaken by that long sustained blast.
This is what I would move psychoanalysis to. If I can. This is to say the analysis cannot proceed until adulthood. The young must be told that is where they are, if need be, and what may need be. I see no problem with the young, as it were, making up their epicentre for future analysis.
The best that can be done is to inform them of the analytical method, the old ways and the new so they may consider it on those problematic to them.
To be certain, I am only working from my own life. I will not be testing anything on another.
