"It's very, very dangerous to lose contact with living nature."

"'In the big cities, there are people who have never seen living nature, all things are products of humans. The bigger the town, the less they see and understand nature.' And, yes, Albert Hofmann said, LSD, which he calls his 'problem child,' could help reconnect people to the universe."

That (though organic sources are better), or being silent and attentive when in a natural environment.
