Dear katy,
Indeed good points.
It's those finer points of caution / protection that are so important of course. And often skimmed over at best. Each are skill sets and subsets within themselves I'm sure you would agree.
This discussion brings up the biggest reason why I don't "walk around with Reiki on my sleeve". And why I often cast a leering eye at many who seek to utilize Reiki for their monetary abundance / income efforts.
Namaste,
Michael
