I learned about the Q-link through endorsements by Robert Bruce and Ken Wilbur.
Basically it is a pendant that uses what they are calling SRT, or Sympathetic Resonance Technology, to help cleanse, regulate, and shield the bodies bio-field. This is even supposed to help protect from exposure to lots of Electromagnetic Frequencies that your are exposed to by sitting in front of a computer writing blog posts and books. If you go to the website you will see all kinds of "science" behind this. I havent done the background work to follow up on them all yet.
The Q link basically consists of a "resonating wafter" that some critics claim is nothing more than a Zero ohm resistor, and a very tightly wound copper induction coil. There are no electronics because the wafer and coil are supposed to work off of the bodies bio-field - what I would call the Etheric Body.
In general I am pretty skeptical of this kind of product. I was struck however by the reviews from some people I respect, and also noted that the BBC did a story on it that seemed to verify its claims with a blood study. Golf Magazine named it product of the year a couple years ago, so I was intrigued enough to get one. Rather than get the resin triangle ones with a big Q in the middle, I went for one of the sterling silver ones with the cool gold pattern in the middle of the copper coil.
I got mine on Saturday and have been wearing it nonstop since except when I am in the shower.
Despite being somewhat skeptical that this was going to do anything, I noticed the effect on my subtle body immediately. For the first hour or so I could literally feel it trying to tune itself to me.
The morning after getting it I made my coffee as always but forgot to pour it. Usually my headache kicks in or I am just so dogged that coffee is the only think on my mind. It was over an hour later that I realized I had forgotten to pour it.
Yesterday I started a new, fairly grueling gym regimen. It wasn't any easier than normal, but I have to say that I was more into it and focused than i would normally be. Given the sorry state of my left tricep today, I probably meditated my way a bit past what I should have attempted.
Usually I dont like to wear much around my neck for long because it gives me headaches. Though it is by no means heavy, the Q link has not resulted in such a headache, or even made itself noticeable at all.
I did a sort of inner body traveling last night, where I collapse my consciousness down into a pearl and travel the channels of the body cleansing them and healing them. There was less cleansing that needed to be done in the energy running to and from the major organs. Also the belt channels seemed to be strengthened, almost like the Q link provides a second layer over them.
I am known to carry different amulets and talismans at different times, but only two that I never leave home without: my Mala and a Phurba*. It's only been three days but I am pretty sure that the Q link is going to be a third constant companion.
To quote Ferris Bueller : "If you have the means, I highly recommend picking one up."
