I understand your response, and think it is good (even scientific) to keep an open mind - fire was once seen as magic too.
I don't have an open mind about sacredness or God being scientific concepts. That doesn't mean I'm closed-minded, as psychonauts like to imply. I'm just wary about scientists veering into this mystical, religious, shamanistic stance.
The point is that those experiences are real and have always been a part of the human condition. There is nothing supernatural about this, nothing bending the realms of physics.
It's all about psychology and how things 'feel', how consciousness works and how it goes beyond the single individual in a group setting.
All that mystical language imho is due to a lack of better words.
