Re: Using Ki. Ki-atsu.
Nice informative post.
I too have met many who do 'similar' things and as you say there are some good, many not so. Here in London there has been A great interest in Reiki Therapy over the last few years but alas, from my point of view, I have met too many who have done a short course and got certificates but.......
As far as Kiatsu goes for me I have done it for many years and as with Aikido or anything really skill and ability is hard learned. It's not therefore the thing, ie: Kiatsu that should be judged but rather how good the person is who is doing it.
