When I tell people they can do they exact same things without taking any form of drugs and more they look at me like I'm the crazy one. That's partly what i meant when I say they only take you to a certain level they're great once or twice as an intro but you don't need them. They won't help you to see or touch “the lines of the world”.

They're not hallucinations either, I get what you mean though. Another thing is that it's too uncontrolled it's easier to learn to get there naturally fully controlled.
