I don't think that anyone can dispute the power of positive thinking. It is the basis of many prayers, schemes, spells and of much corporate teaching. I can personally recall a number of times when positive thinking has, in one way or another, altered my life. The big question, therefore, is not whether positive thinking works, but rather, how it works. I place it on a par with telepathy or with ESP. The former I have personally witnessed many, many times, as I have positive thinking. I rely on others for any facts regarding ESP, but have no misconceptions about its existence. Without actually trying to communicate, I frequently find that I have been thinking of the same thing at one and the same time as my wife, Liz. Indeed before we actually met face to face, we frequently chatted on the Internet - she in Colorado and I in Johannesburg. I would frequently (not just once or twice) be thinking of a particular item or idea (such as the Red Sox) when through the ether would come the question "Did you see the latest Red Sox game?". That was over a distance of 9,000 miles. Today I can be thinking of closing the curtains when up will stand Liz and do just that, with nothing being spoken at all.
I think it's all to do with Quantum mechanics, or that dark or hidden force or whatever. I'm happy with the idea of identical happenings many thousands of miles apart being instantly linked by that quantum forcefield. I don't profess to understand it, but am happy to accept the theory as being a fact. I believe that the same concept is responsible for ESP and indeed, positive thinking. I will try to add an article about this concept to my website.
