My 2 cents...as far as I know it is a dark empath skill...once another empath knows you have that skill...that maybe the last time they want to be around you....or have any type of contact with you again.
I formed a "thread" with that empath...a month before we meet...I was even waking up at the same time she was..I thought it was funny...she did not....and yes I am that pain in the rear empath
So far in the past two months I have meet one empath in person and another four online...and recently a shaman...so far just the one I meet in person knows that I have that skilland blocked me from all contact...but it is just a matter of time before I make a mistake of mentioning my skill to the others.
Explaining how to do it would be the same as explaining to a non-empath how to be an empath.
I used the skill to get my then bipolar wife arrested then hospitalized...quite often she would stop taking her medication...I had no choice to do it....that was 15+ years ago.
The skill does not really turn off...it can stay in your subconscience..it can come up in a fight/disagreement...or even a dream.
Unless they give you permission using it on them it is an invasion oftheir privacy....I do plan to use it in my next long term relationship,with her permission,to allow her to share her feelings with me...I am not sure if I want to share mine..Ithink if I do receive her feelings I will form a bond with her...or nothing will happen.
