I am not sure if many of you guys are familiar with Ingo Swann's work at Stanford (alongside physicist Hal Puthoff), but his website is a treasure trove of information about remote viewing (clairvoyance) and the human potential. Ingo has proven some abilities under very tight controls, and takes a more scientific approach.

He's also got some really cool papers contributed by other writers here:

This essay is fantastic:

THE MARTIAL ARTS AND THE SUPERPOWERS OF THE BIOMIND

excerpt:

Why the older arts have not lost their process of developing the superpower while the modern sport forms have is a point that needs to be addressed. This point was brought home to me one sunny afternoon in Japan.
While walking down a quiet country street, my teacher turned to me and said: "Charles-san, we need to make a gentlemen's agreement."
Having already spent some time with the Japanese and their ways of doing things, I wasn't about to agree to anything until I heard the terms.
In fact, I tried not to look too interested. That way, if agreement was totally unacceptable, no one would (hopefully) lose face. So I just nodded to wait and see what the "agreement" would be.

"You see, Charles-san, your training has to change now, and it will be very dangerous."
You can imagine what I began thinking: DANGEROUS?! I was already nursing a cut where a very sharp and fast moving katana (Japanese sword) had grazed my hand. In those days, we generally trained with "live" swords - that is, very sharp steel ones.

My teacher continued, apparently ignoring my reaction: "And, you see, to do what's next, I will have to train you very hard. So, if I accidentally kill you, I hope you have no hard feelings. Agreed?"

Anyhow, enjoy!
