"You will never know who or what I am, because I don't have a personal
history. The fact that I know whether I am a yaqui or not does not make
it personal history. Only when someone else knows that does it become
personal history. And I assure you that no one will ever know that for
sure.  I have, little by little, created a fog around me and my life.  And
now nobody knows for sure who I am or what I do. Nobody knows my
personal history. Not even I."...........Journey to Ixtlan

So who was Don Juan ? Was this person real ? Or a creation of a fertile imagination ?
These questions are usually pondered upon by peanut brains belonging to the scientific
world. The frustration of not knowing for sure, of not being able to prove this or that
makes them endlessly mired in speculation and confusion.  To add to their confusion,
Carlos,  upon instructions from  Don Juan even changed the names, places and dates
so that Don Juan and his associated people could never be traced by frustarated morons
masquerading as anthropologists. But then they wonder - why were the books written,
if  the scientists can't verify everything for themselves as in a proper scientific procedure?
It seems impossible for them to understand that there can be anything outside the scope
of scientific investigation, and that someone should refuse to make themselves available
as guinea pigs for the noble cause of scientific research.

"If you have no personal history, no explanations are needed ; nobody is
angry or disillusioned with your acts. And above all, no one pins you down
with their thoughts, and that makes us free from the encumbering thoughts
of other people."

One thing is for sure. Don Juan did successfully erase his own personal history, though
Carlos was not that successful with his.

But a personality is something that can't be erased. And that is what comes through very
strongly. A personality of a very unusual human being that defies categories and labels.
A Shaman ? But even that label does not seem to apply on him. A personality that can
only be described in his own words :

"A diablero is a diablero, and a warrior is a warrior. Or a man can be both.
But  a man who only traverses the path of life is everything.
Today I am neither a warrior nor a diablero.
For me there is only the travelling on the paths that have a heart,
on any path that may have a heart. There I travel, and the only
worthwhile challenge for me is to traverse its full length.
And there I travel - looking, looking breathlessly."
