^^ I think what PIP is saying is that shamanism incorporates any-possible-and-every-thing: the experience manifests in a personal manner for the practitioner.
I'm glad yagecero that you say the shaman isn't there to 'interpret' the visions for you. I found the idea of someone sitting next to me during an ayahuasca ceremony, telling me what I was seeing according to some mystical beliefs I don't necessarily ascribe to, disconcerting.
Wouldn't it be disconcerting. A proper ceremony will be mostly silent for the majority of the time in very low, almost dark, candle-light and when there is sound, it is the shaman (or other experienced drinkers/apprentices) singing an icaro or playing an instrument. Nobody talks during the ceremony (except for spontaneous breaking into song, speaking in tongues, screaming that one is about to die, groaning etc. lol that occurs from time to time), everyone has their own little space and they spend the time inside their head.
The shaman doesn't say anything unless you ask him something directly.
But I've also been told that doing ayahuasca in the wrong environment, and without a shaman, disrespects the substance.
I don't agree with this at all. The issue is one of respect for the process. Both apprentices that I know drinking frequently by themselves in their homes. Do I think there is something to be gained from drinking in a traditional setting? From a personal perspective, yes.
In my case, the opportunity came up recently to meet with someone who's apparently a shaman, and charges for 'cleansing' sessions, but I haven't been able to get in touch with him. I'm skeptical of this sort of thing, especially where money comes in.
An Amazonian shaman will charge $20 for the experience if that puts things into perspective. I know that there are "shamans" in my city in Australia that charge exorbitant fees for their "services", and while I haven't met them personally, I would be reluctant to get involved with this scenario as well.
The thing is, I wouldn't know how to distinguish between an outright fraud, someone who actually thinks they have shamanic powers, and someone who actually does have shamanic powers - if they do indeed exist.
This is an enormous issue - there are many charlatans in the jungle now, and even more in the west, but let me put it logically without dressing it up in spirituality: A shaman is fundamentally a super experienced trip sitter. Through thousands of experiences with the plants that s/he works with (under the guidance of someone that is even more experienced during their apprenticeship), a shaman learns how to manipulate the effects a participant experiences after imbibing, through music, song, various actions and movements, and can guide someone's journey
IF NECESSARY (they will usually leave you alone to talk to a tree or whatever you're doing at the time, which is usually just lying in a hammock). In this sense, a shaman is also a therapist of sorts. S/he knows what to do when various issues arise during a ceremony and can change the course of the experience with sound and movement/action.
However, I'm open to exploring shamanism, particularly because I sometimes feel a sort of affinity to native American culture and their depictions of altered states.
Any shaman worth your while will directly tell you that you are equals and that it is the plant that is the teacher, not them. The thing I really dig about a traditional ceremony is the silence (with jungle noises in the background) because without music playing (which in the west is a given during almost every psychedelic experience) the experience becomes audible as well. Music comes from no(some)where and it's truly magical.
And just on a personal note, there is NO better location than the jungle for a ceremony.
*Obviously I'm referring predominantly to the Ayahuasqueros of the Colombian Amazon.
