> Sure, I had read various books about opening the doors of perception but at some point you realize it's just more "you" that you are finding.

But that's what opening the doors of perception means. Of course you're "only" discovering things about yourself, but that is still valuable and I think that is what a lot of people find 'mystical' about these drugs.

I agree that shamanistic woo-woo doesn't do any good though.
