If the animal is too tense or agitated and doesn't submit it isn't slaughtered, simple as that, no questions asked. As you might suspect, it isn't a very industrial/commercial approach.
Yes, Dmt-nexus is really a refuge, for sure. It's a shame that some people only want to know the technical aspects of DMT extraction (or other substances) but not the human aspects of it (ritual, meaning, mind investigation, etc). In my humble opinion, nexus has a way more mature ethics and drug approach than many people out there that think that "harm reduction" consists in prohibiting every substance, and makes society deal with violence and drug trafficking. But I will not get myself into that kind of discussion here, since it goes against forum policy (no politics policy).
As always an interesting point, Void. For sure, reality is not an objective thing and has values and interpretation in it. I'm just thinking how we, modern western homo sapiens would deal with "pre-modern" or ancient approach of reality. I've read a book once that made it even more tense, which name is "The Falling Sky: Words of a Yanomami Shaman" that is a classic in south american anthropology, originally written in french (La Chute du Ciel: Paroles d'un Chaman Yanomami) is a Yanomami Shaman trying to explain many things to western man, among them, the psychedelic shamanic experience, and a very interesting "reverse ethnography" (since he observes and talks about the white man in a really original way).
Thank you for reading it. Just answering the question of a fellow forum member.
