“…the brain is like a TV set that is “hardwired” into the single “channel” of everyday physical reality — Rick Strassman calls it “channel normal.” What psychedelics may do when used and administered properly is “retune the receiver wavelength of the brain,” thus providing us with regular, repeated, reliable access to other levels of reality that surround us at all times but are not normally accessible to our senses. It is even possible that these long-reviled drugs open a secret doorway inside our own minds allowing us to approach the Holy Grail of quantum physics — freestanding parallel universes and the intelligent beings who inhabit them. If that is so then the ability of psilocybin to release terminal cancer patients from their fear of death through “an abrupt change of consciousness” makes perfect sense — for they would know from direct experience that even when the television set is broken the television signal keeps right on broadcasting.”
