Because it is in my nature to ask question, like why.
What I know about scientific studies show, that altered state uses aplha brainwaves, ok. I've heard human body can exrete small amounts of DMT and alcohol, has those any role in spiritual experiences is just interesting.
But more it is with that, what Dr. Iron said: " It is not the potions themselves, but how you use them."
There was a time, when I was heavily drunk, and it turned spiritual experience without much any reason. For example my face started to show complately different faces for a friend of mine, maybe from ancient past do not know and I was just feeling present, letting world turn around me. Same time friend was experincing to be a dog. Just wondering what may cause that. It was only alcohol and incence we used there, no hallusinogens.
And also, there are those times, when nothing were used at all and spiritual realm has come very close. Maybe that is reason also not to do journeys much anymore, but relaying more in dreams. No need for rituals or potions actually.
But, yes to make potions to work ritual gives it a contects. With scientific approuch, I am curious with the difference, when brainwaves are changed to alpha and that way perception of reality changes and what happens when drugs are used and what makes it spiritual?
I am tracking the processes of mind losing control, so spirit can be experienced. I am thinking, what Rachara El said, that there is danger to become too open, and you are going to lose yourself. I bet all have heard about those chemistry involved "trips", which sadly never ended.
Same thing has happened with yoga also, when nervoussystem is not strong enough for kundalini to rise, and result leads to kundalinipsychosis. Which has same kind of symptoms with hallusions and inabilty to come back into range of ordinary perception, as those taken LSD too much.
There are great deal of people near satgurus as deciples and it is not only enlightment they get. Suicides and mental illnesses do occur also quite often, which is not very often publicly talked about. But for centuries in attempt to face god people are driven themselves mad.
In that light I do like to learn about dangers and how to walk path with understanding of whole process, being yogateacher, when yoga is understood as science of spirit.
Connection to spirit seems so far to be just removing obstacles like mind, selfconsciousness away, which may be helped with different substances, sounds, movements, physical exertion. Nothing of these however seem to guarantee anything. So we come back to openness and maybe surrendering as key factors. Is openness and "losing mind-control" enough? Everybody need to keep intention strong to do meaningful journeys. Whether it is to just sit and being with god, where is no thoughts. Hmmm... I think I get something. Thank you!
