No it's not - if you get a good practitioner.
My dad does it - but not for money. He just treats his cat and me sometimes.
The heat that radiates from his hands is unreal and he doesn't actually touch your skin.
I had a twisted womb and was told I've never have kids. He hovered his hands over me and I felt like I was punched in the stomach. It was the weirdest thing feeling things move inside me.
I am the most cynical person ever and don't believe in anything woo.
I've got two kids now. And he's cured so many headaches and minor things like sore joints.
Our cat was squashed flat by a wardrobe as a kitten and he treated her. She lived to be 19 with her weekly reiki sessions.
My dog was hit by a car and the vet said he wouldn't likely walk properly again. The day after he had reiki he got up and walked. It was very emotional. This was 9 weeks in and we thought he would drag his back leg forever. However he HATED when grandad put his hands over him. He's a very chilled dog and he would tolerate it for a few mins but then the heat got too much. He wouldn't go near my dad for weeks after. But once he was back to normal they were besties again.
So I think there HAS to be something in it if the reiki person has the gift.
Surely it can't be placebo?
