NET is a separate modality of its own - http://netmindbody.com. It uses muscle-testing to find the belief or trauma causing the undesirable behavior or response, then a short meditation to release it.
I understand it's similar to Psych-K, but I've not tried that - though I am interested.
I have done tapping and initially found it beneficial but soon hit diminishing returns. I've since read a few things that express the view that tapping can be harmful.
When I started out with NET I'd visit a chiropractor, but recently I've learned how to do it myself, which saves me a lot of time and money and allows me to progress much faster.
Appreciate the reply very very much. I've found psych-k and tapping both revolutionary for handling rapid onset emotional issues. I'm going to learn NET too, now.
