It seems, from research i have done so far and in my opinion, that we are all empaths to some degree. The article below explains some of the noticeable elements you might see in a person who has a highly empathic nature but i believe that everyone may show some of these qualities, even narcissists, infact, I question that it might be possible that narcissists could have at some point been highly empathic but they have reacted to negative conditions and have closed themselves off.
Fully empathic people are pretty rare as many people do close down sides of themselves as protection but it is always possible to reverse the process by doing the inner work and using therapies such as Reiki to release the inner blockages.
Imagine the world full of Empaths…..an interesting thought.
