Before October slips away, I wish to acknowlede your courage in mentioning brujeria. The topic is one that my writings touch upon. And you are spot on in describing it as "a pretty distasteful topic". My own and my shamanic teacher's personal experiences certainly have confirmed this.
Predatory animism is real and its power indeed is underestimated by most Westerners.
I have another question about an indigenous transmission that seems to be surfacing in different traditions and places. If you're still around, I will post it later today.
