I know there's a language barrier here, but please don't just post statements like, "They taught him shamanism and spells" about Indigenous people unless you know for a fact, from those exact Indigenous people, that these statements are true. Because they are almost always lies.
Please don't say these spiritual tourists are "friends" of the cultures they exploit, even with a question mark.
Every single person you've asked us about so far has been some kind of grotesque, grandiose confabulator when it comes to these claims, making outrageous exaggerations and mistranslations/misinterpretations at best, or, in most cases, totally offensive and blatant fabrications about Indigenous people.
Spiritual tourism is very common with these frauds. They exploit people. It's ugly. They hop a plane and take some drugs and take a photo with a random brown person then they say whatever they want. And no, Celtic Shamanism didn't and doesn't exist. There were and are spiritual traditions but it's not like the Harner shameon stuff that these people sell. It's what white appropriators of Native ways say when they know nothing about Celtic cultures, either, and they're hoping the other white people are as ignorant about those ways as they are about Natives.
Like we've said in other threads - it doesn't matter if he met someone, or if he stalked some people in a community, or even if he paid for some drug trips. That doesn't mean anything. Natives don't exist to give white exploiters cultural or ceremonial secrets. Drug tourism is very popular and, sadly, some people who desperately need (or just want) the money have fallen into providing that for the tourists. That's why the medicines are endangered and the traditional people are desperately worried what is going to happen to their ways due to this exploitation. It's horrible. See all the threads we have on this. What's different about this guy?
