I have found the best to my consciousness definition of
a Toltec in one book of
Theun Mares.
I have lent all my Theun Mares books to a friend so I can't find it and share it excactement (thats French)
I recall being said that one earns the title of Toltec (for sure) after being "passed" the forth enemy of man, old age, which is also known as the 90 degrees turn or so
I recall also being written that somebody is Toltec for only a short period of time or something like that - but that may be wrong..
