Psychedelics are illegal not because a loving government is concerned that you may jump out of a third story window. Psychedelics are illegal because they dissolve opinion structures and culturally laid down models of behaviour and information processing. They open you up to the possibility that everything you know is wrong.
Terence McKennaThe real truth that dare not speak itself, is that no one is in control, absolutely no one... Nobody is in control. This stuff is ruled by the equations of dynamics and chaos. Now, there may be entities seeking control - the World Bank, the Communist Party, the rich, the somebody-or-others - but to seek control is to take enormous aggravation upon yourself... It's like trying to control a dream.
Terence McKennaThe Truth doesn't need your cooperation to exist. All forms of cult, all forms of hype, all forms of delusion do require your participation in order to exist. I've looked into marginal areas of human experience -historical and otherwise- with a rational mind, and what I've found is that doorways into the miraculous are far fewer than the publicists of the New Age would have us believe. On the other hand, they are not as rare as the proponents of radical reductionism and materialism would have us believe. There are doorways out of the mundane.
