Normally, teachings that involve drugs bother me to no end. It's a concept that just doesn't sit well with me. However, somehow this book is proving to be an exception to that general rule. Drugs, in my opinion, have a tendency to complicate spirituality. They often orient seekers towards intense spiritual experiences, but in a way that I find rather concerning. To me, they seem like a great form of laziness. It would be fine if they were actually more effective than they are in achieving true spiritual growth. But all too often, it just boils down to rich white kids who have watched "The Matrix" one too many times and think that taking drugs will give them some sort of instant enlightenment.
Again, in the case of Don Juan, the drugs occupy a very secondary position. Foremost, most of the drug experiences described are actually quite terrible. They are used for specific teaching purposes, usually related to some form of power. Second, Don Juan is a trickster and appears to be tripping up Casteneda in every way possible. The drugs seem more like very intuitive beatings than cool experiences. I can't help but think that it's a strange and rather unorthodox way of teaching. I would only hope that I might one day have someone to guide me and challenge me like Don Juan did with Carlos, but perhaps without the need for drugs.
