Humans are the hapless, ignorant, trappers of their brethren.
I have written about the client who, without asking me, went and done an Ayahuasca retreat, then continued to drink that stuff after he returned home.
Result: I needed to do 200+ dollars worth of work on him, 200+ dollars worth of work on a friend of his, and then 200+ dollars worth of work on me.
These are the people who we know were effected.
The spells (attachments) were debilitating and painful. I experienced them both directly and indirectly.
