[1] According to Paul Krassner in Los Angeles Times, "Turn Off Your Mind offers an alternative chronicle of what went on in the '60s when, somewhere along the spectrum of expanding consciousness, many hippies collided with a fascination with black magic.

Krassner wrote: "I suspect that, unless you are a hard-core enthusiast of occult esoterica, you will find reading this book a chore rather than a pleasure.

If you want to know about, say, beatnik king Brion Gysin, ley-line apostle John Michell and Zen master Alan Watts, this is the place to start.
