For a first time user of psychedelics I think there is a bit of 'whoa, it's possible to see things differently', with a hearty dose of 'I felt completely calm and at ease for a while'. You come out of the experience refreshed and rejuvenated with your new perspective in your back pocket, but the world remains essentially the same.
What I think differs from person to person is their interpretation of the experience, which usually ends up driving a world-view that probably already existed, whether secularism, or some other form of spirituality.
it's a powerful experience; a rebirth. The person going in will not be the person coming out.
Not arguable but the question is, will that "reborn" person have a better understanding of reality or an understanding that has been confused by the experience but which they mistakenly believe is clear.
This.
Lots of drug users who are hopelessly lost in their own head who think mentally altering their perspective somehow equals meaning.
To me the real doors to perception are books. Literally understanding the world around you. Some of the greatest relief I've gotten from my problems is literally just that: actual perspective.
