Many years ago I was stopped in a UK high street by a saffron-robed mendicant who offered me a free book (in return for a donation, which I found an amusing definition of free). I refused it, but for some reason the title stuck with me: "Easy Journey to Other Planets".

Even in later years when I researched lucid dreaming and remote viewing, I never actually got around to getting and reading it - anyone else able to save me the trouble and let me know if it is worth the time?

There is another great book on the subject, The Yoga of Dream and Natural Light my Namkhai Norbu and Michael Katz. It's kinda fascinating that a thousand years ago Tibetans were exploring this fascinating subject in depth - with precise methods, scriptures and so on - while at the same time in Europe theologians were debating how many devils could be fit on the tip of a needle.

The latter was a debate about materialism, and whether the divine had any physical component (in which case there was a finite number of angels on a pin), or did not (and therefore infinite), with consequences for the debates about whether divinity is a falsifiable hypothesis.

Intelligent people were having intelligent debates.

It's as though even the European theologians were embarrassed and were simply trolling with thought experiments like that.

Your comment is akin to saying “it’s so embarrassing that Plato was having thought experiments about spelunking.”

Your comment — and the one to which it responds — is cringeworthy.

It doesn't make logical sense. How people can enter one anothers dreams? We can not see whats going in another person's head.
