Although Carlos may have made up most of the stuff in his books, even the made up parts are quite fascinating and instructive. Let's briefly cover his (the supposed Nagual) notion of "impeccability". There's a moral component to this only to a degree, since an evil sorcerer can take care to be impeccable within karmic limits. Foremost, one must undertake various practices to insure that one is protected from psychic attacks by other sorcerers, especially. But like the "good-Spy/ bad-Spy" comics, there's no absolutely foolproof protection. Such protection is evolutionary, akin to the various types of strategies undertaken by insects, birds, and other creatures to enhance their own protective devices while at the same time gaining an edge on the next meal. ... By way of examples, if somebody is assassinated - like Tat Walla Baba (in spite of a strong psychic shield); or in the case of Gandhi, well we can say that although in the first case, Tat was well aware of impeccability strategies but failed due to bad karma. Gandhi covered himself with a huge amount of good karma and had millions of followers, but for some unknown underlying karmic reasons coupled with more obvious causes, there was a chink in this psychic armor - right in the chest. ... Now getting to MMY, somewhat separate from his messing around with the female followers; it';s quite obvious that the man knew virtually nothing about the concept of impeccability and his psychic armor (if any - due to multitudes of yagyas); had so many holes it that he was like that old Jerry Lewis movie where he was inducted into the Army and had lots of shots. Spouts of water spewed out of the holes. ... As "Nagual"'s go, MMY was a total embarrassment to the concept of impeccability. What a disgrace!
